Bumbleby

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

Canon
Their first interaction was in Volume 1, 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. Although, when they're picking partners, she seems happy to be Blake's partner. Even though Blake is known to be the cold and mysterious person in the team, Yang makes her smile on several occasions after they become partners.

In the episode Burning The Candle, Yang tries to get Blake to relax from investigating the White Fang and just attend the dance. She confronts her and actually got her to go after relating to her and showing her that she cares about her a lot. Yang then, states that if Blake felt like "coming out," she would save her a dance. In the end, Blake does come to the dance with Sun Wu Kong, but shares her first dance with Yang.

In the episode Heroes And Monsters, during the battle of Beacon, both Ruby and Blake are missing. Wiess tells Yang this, and Yang chooses to find Blake rather than her missing sister. Meanwhile, Blake is fighting Adam Taurus, and after overpowering her, Adam says that he'll "Destroy everything that she (Blake) loves". And upon seeing Yang's arrival, he 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 in pain. Her cries are heard by Yang, who gets angrier than she ever has in the entire series, and in a blind rage, recklessly charges at Adam, only to get her arm taken off by him. She then loses consciousness. Adam moves forward to finish her off, but Blake sends forward one of her shadow clones to distract him. While he is distracted, Blake grabs Yang and escapes.

They are later shown, with Yang still unconscious, and Blake holding her hand weeping, stating over and over again that she's sorry. Do to her feelings of guilt over what happened to Yang, Blake leaves team RWBY and runs away to her family in Menagerie. This greatly upsets Yang, because Blake left without even so much as saying goodbye.

Volume 4 and 5 does not have any physical interactions between the two, but there are moments when they talk or mention each other. Yang mentions on several occasions that she doesn't understand why Blake left. Then later states, that maybe she needed Blake to be there for her. On another occasion, Blake expresses the guilt she feels for what happen to Yang to her friend Sun Wu Kong, he replies that both he and Yang would gladly go through what they had, if it meant protecting Blake again, and that running from her problems to "protect her friends" doesn't solve them, it only makes the problems worse and hurts her friends. In Volume 5 Episode 14, Blake is finally reunited with her team at Haven. Despite both Blake and Yang's hesitation, the two are reunited, and the entire team RWBY shares a meaningful group hug.

Throughout Vol. 6 there are several instances in which Yang and Blake hold hands and give each other long glances. Several more noticeable moments are: In chapter 5, Yang is still suffering with the PSTD from her fight with Adam, Blake attempts to comfort her by holding her hand and then by promising Yang that she won't leave her and that she will protect her as well. Which Yang didn't take very well. They make up later, when it discovered that they, along with the rest of team RWBY, were under the influence of the Apathy.

Then is episode 10, when Blake is alone on a mission, Adam ambushes her, and engages her in a fight. During this fight, Adam disarms Blake, and proceeds to physically and mentally abuse her. Finally he makes to kill her, but asks first, "How does it feel to be alone?" Blake, hearing the sound of Yang's approaching motorcycle replies, "I'm not alone." Yang arrives on scene, and proceeds to fight Adam. As they fight, Yang's PTSD starts to act up. Adam, noticing this starts to taunt her, saying that Yang was going to die trying to protect Blake. Blake takes Yang's trembling hand and says, "She's not protecting me, Adam. And I'm not protecting her. We're protecting each other." And together, they proceed to fight and eventually kill Adam. After his death, Blake breaks down weeping, and Yang rushes to her side to comfort her. As Yang embraces her, Blake tells Yang that she "won't break her promise." Yang then cups Blake's face and replies "I know you won't." They continue to embrace and even share a moment of looking into each other's eyes. In the last episode, when discussing what happen to the rest of team RWBY and JNPR, Wiess Schnee comments that "at least she(Blake) had Yang with her." To which Blake agrees, and Yang takes her hand and they share another meaningful look.

Fanon
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.

In the episode Downfall, Blake is finally reunited with her team after running away at the Fall Of Beacon. Despite being in a room full of people who also haven't seen and worried about her, the only name she says is Yang's. This helps the fact that Blake and Yang really did miss each other equally as they both almost breakdown just talking about each other when they're separated.
