Bumbleby

Bumbleby is the femslash ship between Yang Xiao Long and Blake Belladonna from the RWBY fandom.

Volume 1
Their first interaction was in Chapter 3, when Yang wanted to help Ruby make new friends. Blake at first seems to have no patience with the two, only wanting to get back to her book and being alone. After stating so, Yang proclaims Blake a "lost cause" to her sister. Though, when they happen to become partners in Chapter 6, she seems happy to be Blake's partner. Even though Blake is known to be the cold and mysterious type, Yang makes her smile on several occasions after they become partners.

Volume 2
In Chapter 2, Blake is adamant about finding out what Roman Torchwick is plotting. After Ruby proposes they start planning a day to do so, Yang gets excited and turns to Blake saying, “I love it when you’re feisty.”

In Chapter 6 titled Burning The Candle, after losing Torchwick a second time, Blake dedicates all of her hours trying to investigate him and the White Fang. Because of this she doesn’t sleep and acts cold towards her friends. Yang decides to try and get Blake to take a break and attend the upcoming school dance. After leading Blake to an empty classroom, she opens up about her own childhood struggles, explaining how her mother abandoned her and she’s been searching for her for years. But she won’t let that search control her like how Blake’s search currently is. Blake argues with her at first, until Yang hugs her and tells her that she doesn’t need to stop, but she should get some rest, “not just for herself, but for the people she cares about,” showing that she cares about Blake's health and well-being. As Yang is about to leave, she turns around and winks as she says to Blake, “And if you feel like coming out tomorrow, I’ll save you a dance.” In the end, Blake does go to the dance with Sun Wukong, but shares her first dance with Yang.

In Chapter 10, Yang can’t sleep and asks Blake if she is awake, which she is. This leads to a discussion (that Weiss eventually joins) about why they want to be huntresses. Blake goes on to open up a bit about her past, revealing that she had an old partner named Adam who became a “monster.” She becomes wary of what her future will be once she leaves Beacon, and Yang reassures her by saying “I’m sure you’ll figure it out. You’re not one to back down from a challenge, Blake.” This shows that she genuinely believes in her, even if Blake may not think the same of herself.

Volume 3
In Chapter 11 titled Heroes And Monsters, during the battle of Beacon, both Ruby and Blake are missing. Weiss tells Yang this, and Yang chooses to find Blake rather than Ruby. Meanwhile, Blake is fighting her old partner Adam Taurus, and after overpowering her, Adam says that he'll "destroy everything that she (Blake) loves.” Yang arrives, calling out for Blake, currently unaware of their presence. Adam points at Yang saying, "Starting with her.” Blake is horrified, and her facial expression gives this away, confirming Adam's assumption. Adam then stabs Blake in the stomach with his sword, causing her to cry out in pain. Her cries grab Yang’s attention, who then yells at Adam to “Get away from her!” When he doesn’t, she charges at him in a blind rage, tears in her eyes, ultimately getting her arm amputated by Adam and losing consciousness. Adam goes to finish her off, but Blake sends forward one of her shadow clones to cover Yang’s body. While he is distracted, Blake grabs Yang and escapes.

They are later shown lying on the ground in the courtyard, with Yang still unconscious. Blake holds her hand, weeping and stating over and over again that she's sorry. Because she blames herself for what happened to Yang and feels immense guilt for it, Blake leaves team RWBY and runs away to her family in Menagerie. This greatly upsets Yang, because after all they had gone through, Blake left her without saying goodbye.

Volumes 4 & 5
Volumes 4 and 5 for the most part do not have any physical interactions between the two, but there are moments when they talk about or mention each other.

In Volume 4 Sun is wounded by Blake’s former friend, Ilia Amitola. When Sun wakes up, Blake explains that the reason she ran away was because she blames herself for the people around her getting hurt, especially Yang. She says that they shouldn’t have to fight her battles for her, that she alone should deal with the consequences and that if she left they would never be hurt by her past ever again. Sun thinks that’s ridiculous, and replies that they help her because they want to, and both he and Yang would gladly go through what they had again if it meant protecting Blake. Sun also tells Blake that running from her problems to "protect her friends" doesn't solve them, it only makes the problems worse and hurts the people she loves.

Yang mentions on several occasions that she doesn't understand why Blake left, and at some point is doubtful if she will ever come back. When having a talk with Weiss, she states, “What if I needed her (Blake) here for me?” And begins to cry as Weiss reassures her that Blake will come back and that she just needs time to heal.

In Volume 5 Chapter 13 during the battle for Haven, Blake walks into the school to see all of her old friends and classmates. Despite this, the only thing Blake says is, “Yang?” Yang looks at her in awe because out of everyone who has ever left her (without giving a good reason first), Blake was the only one to come back. In Chapter 14, Blake is finally reunited with her team. Despite both Blake and Yang's hesitation, the two are reunited, and the entire team RWBY shares a meaningful group hug.

Volume 6
In the beginning of Volume 6, Blake tries to make things up to Yang by insisting that she help her get her bag. Yang tells her that she doesn’t need to do that saying, “We’re gonna be fine,” meaning her relationship with Blake, also adding that she’s glad the whole team is back together.

In Chapter 5, Blake suggests that her and Yang search other buildings in the town they are staying in for vehicles. Yang gives her the cold shoulder, even ignoring a joke that Blake makes when they walk into the shed. When they find something, Yang looks outside of the window and panics when she sees Adam there for a split second. Her PTSD triggers her hand to start shaking, as she explains to Blake that she “still gets flashes from that night.” At this, Blake takes Yang’s hand in hers and promises that she’s not leaving and that she’ll be there with her if Adam ever comes back. However, Blake also says that she’ll protect Yang, which she doesn’t take very well. It made her believe that Blake thinks she isn’t strong enough to go back up against Adam, and she pulls her hand away from Blake’s.

They later make up when they realize that they had all been under the influence of the Apathy. When they are able to escape the Apathy in Chapter 6, Yang grabs Blake’s hand and runs out of the house with her.

In Chapter 10, Blake is tasked with shutting down the communications tower to help everyone steal an Atlas airship. Yang takes her there on Bumblebee, her motorcycle, with Blake holding onto her. Just as she is about to leave, Yang asks if she should come with her. Blake tells her no, and almost responds with a playful insult to Yang’s semblance, but covers it up saying that “You're great! And I’ll hurry back.” Yang smiles, telling her to go, and keeps gazing at her long after she leaves.

In Chapter 11, before Blake is able to disable the tower, Adam Taurus ambushes her. Blake realizes that the times she thought she was just imagining Adam there, in reality he had stalked her across Anima. They begin fighting, Adam continually harming Blake both physically and mentally before disarming her. Finally as he prepares to kill her he asks, "How does it feel to be alone?" Blake hears the sound of Yang's motorcycle approaching in the distance and replies, "I'm not alone." Yang then drives off of the cliff above them, launching herself off of Bumblebee and landing next to Blake as the motorcycle proceeds to run Adam over. Yang and Adam begin fighting, and he taunts her to a point where her PTSD starts to act up. Adam asks Yang if she’s just trying to scare him away so she won’t have to die trying to protect Blake. Blake takes Yang’s hand and says, "She's not protecting me, Adam. And I'm not protecting her. We're protecting each other."

In Chapter 12, Blake and Yang continue to fight Adam together, before he is able to land a hit on Blake which sends her off the edge of the cliff. Luckily she is able to hang on, but now Yang is left to fight Adam until she’s able to get back up. At some point Adam yells, “What does she (Blake) even see in you?” Yang uses the lessons her father taught her in Volume 4 to disarm Adam, and throws his sword off of the cliff. When Blake eventually comes back up, she and Yang use her broken sword to stab Adam. He falls off the edge and into the water below, now dead. Blake begins to shake and falls to her knees, sobbing. Yang quickly rushes to her side to comfort her, pulling her into an embrace. Blake swears she’s never going to break her promise. Yang then brings her hand to Blake's face and replies "I know you won't." They touch foreheads and continue to hold each other, Blake putting her hand over Yang’s in the process.

In Chapter 13, when they are able to leave Argus in the Atlas ship, Blake apologizes for not being able to disable the tower. Yang sits close to her, and reassures her that what had happened wasn’t her fault. Before Blake can protest, Ruby interjects and says that all that matters is that she’s safe. Ruby pulls Blake into a hug and looks at Yang, who smiles at her before looking away, Ruby seemingly understanding how she feels.

Later on Weiss says to Blake that she’s sorry she had to “go through that nightmare” but is glad Yang was there for her in time. Yang then places her hand over Blake’s and says, “We were there for each other.” The two share a meaningful look and Blake's eyes seem to dilate a bit.

Volume 7
Throughout the entire volume Blake and Yang can be seen looking at each other at various points in time. They also fight solely together more often than not.

In Chapter 3, everyone receives an outfit change and Blake cuts her hair. When they are receiving details for their new mission. Blake realizes Yang is looking at her, who starts to fumble slightly after being caught saying, “Sorry! Just… not used to the new hair yet!” Blake smiles and visibly blushes, asking her if she thinks it looks bad. Yang, not wanting her to get the wrong idea, quickly responds, “No! No, it’s good, great even!”

Since Blake’s weapon was broken at the end of Volume 6, her weapon receives an upgrade as well. Her sword was mended back together with gold, which is a method known as Kintsugi. The gold can be perceived as a reference to Yang as she is associated with the color gold on multiple occasions throughout the show. It is also implied that Blake specifically requested her weapon to be repaired this way.

In Chapter 4, during their “graduation” party, Yang runs up next to Blake and starts taking selfies of them together. Blake was surprised at first but smiles anyway.

In Chapter 5 during the morning montage, there are flashes of team RWBY progressively getting more and more tired up to the point where Blake falls asleep on Yang’s lap, and Yang rests her hand on her arm.

In Chapter 6, after being told that everyone has the night off for the election, Blake is seen putting on makeup while Yang looks at her from on her bed. When Ruby asks where they’re going, Blake says that team FNKI invited her and Yang out dancing. When Ruby brings up the fact that Yang thought team FNKI was annoying, she replies with “That’s the best part about dance clubs. 'I can’t hear you'”, which causes Blake to laugh. A few moments later, Yang starts laughing as Blake attempts to copy a dance move that Yang had shown her. Yang demonstrates again, and Blake insists that she was doing the same thing, causing them both to laugh. Later in the episode, at Robyn Hill's political rally, Ren and Nora try to work out aspects of their own relationship. In doing so, Nora compares their relationship to Blake and Yang's, commenting "Friends, huh? Just friends?", implying that she knows they have romantic feelings for each other.

In Chapter 7, Blake and Yang are sent to ambush Robyn Hill. They have a vague conversation about what happened with Adam, Yang telling her that they “did what they had to do.” Blake understands that but says she doesn’t want to have to resort to killing someone again. Blake then expresses her opinion on their current situation and doesn’t want to ambush a huntress who’s just trying to help. Yang ends up agreeing with her, and together they go against orders to tell Robyn about what Ironwood has been doing. When Ironwood eventually finds out they told her about the Global Communications Project in Chapter 11, Yang defends Blake.

In Chapter 9, Blake and Yang look at Ren and Nora holding hands before looking back at each other, smiling.

In Chapter 12, Blake and Yang use their tag-team prowess to defeat the more "experienced" Ace Ops in combat after Ironwood turns on them due to his paranoia after Salem makes herself known.

Fanon
Bumbleby is considered one of the most popular ships in the RWBY fandom, possibly even the most popular.

In the episode Burning The Candle when Yang tries to convince Blake to come to the dance, she hugs Blake and says "And if you feel like coming out tomorrow... I'll save you a dance". Yang is always known for her puns and this could be referencing "coming out", as revealing your sexuality. It could also mean just going to the dance. But, many fans of the ship see this scene as the former. Unfortunately, it has also drawn hate from "fans" who say that Monty never wanted this and go as far to say that the voice actresses for Yang and Blake should be fired for supporting the ship. They also believe that the CRWBY are being "forced" to "change" the storyline because of shippers and refuse to accept any of the evidence shown, saying it "doesn't count". These people also reacted to Arryn confirming Blake is bisexual by saying that they were "turning her gay to satisfy the toxic shippers" which is not true at all.

On AO3, Bumbleby is the most written ship for both Blake and Yang. It is also the most written ship in the RWBY tag.
