Scollace

Scollace is the slash ship between Scott Pilgrim and Wallace Wells from the Scott Pilgrim vs. the World fandom.

Comics
Scott and Wallace first meet in college when Wallace approaches him during a lecture and starts inserting himself into Scott's life until they become friends. (In a manner that parallels one of Scott's high school love interests, Lisa Miller.) The two later become roommates - a story that Scott describes as "somewhat gay" to Kim.

As roommates, Scott and Wallace share a futon as they cannot afford two beds. Wallace also owns most of what's in their apartment and pays for all of Scott's expenses as he does not have a job, to the point where Scott literally keeps Wallace's credit card in his wallet. This has led to Wallace referring to Scott as "his bitch forever." and Scott is frequently spotted wearing Wallace's clothes, although it only gets mentioned once.

It is frequently brought up how Scott is a complete mooch to Wallace but he never seems bothered by it and actively pampers him in various ways - such as cooking for him, wrapping him up in a blanket and giving him hot cocoa when he was freaking out and taking him out for sushi.

In fact, despite how much Wallace regularly teases Scott, he genuinely cares for Scott's well-being. The few times Wallace is shown to be angry have always been about how Envy Adams broke Scott's heart. When their lease was up Wallace offered to stay with Scott for as long as he needed since he knew Scott couldn't afford his own place. (Although he later said that he had already signed a lease with Mobile beforehand.) He continues to offer support and advice to Scott even after they stop becoming roommates and houses Scott for a while when Ramona briefly kicks him out of their flat. It is implied that they shared a bed together again then as Scott became flustered and said that he did not need to answer when Ramona angrily asked if he slept on the couch or on Wallace's bed.

After Ramona breaks up with Scott, Wallace was once again there to support him. He makes breakfast for Scott and jokes about how he has Scott's body to play with instead when talking about how his boyfriend Mobile was away. This is one of the many flirtatious comments Wallace directs at Scott, such as calling Scott hot when he is complaining about his hair, referring to Scott as "baby" several times across the comics and often sending flirtatious texts directed at Scott to Ramona's phone (as Scott does not have his own) to the point where Ramona feels like a personal secretary for all his "little mash notes".

Movie
Unlike the comics, Wallace is much more calloused and vocal about wanting Scott to move out and get his shit together. Most notable, however, is the fact that he brings multiple men to sleep with in their bed across the movie, and they all just casually wake up beside Scott the next day. (Scott was even shown to be between them and Wallace in one of the original storyboards.)

He also offers emotional support across the movie, be it cheering Scott on during fights or making hot cocoa for him when he's down. Scott also begs for him to not go when panicking about his date with Ramona, to which Wallace says to meet up later whenever he decides to bail. He encourages Scott to fight Gideon after he takes Ramona, which happens right after Scott comes home and accidentally walks in on Wallace having sex. In the deleted version of this scene, Wallace offers to let Scott stay again and gives him blinkers and earmuffs to avoid having to see it. Telling Scott that he loves him and is thinking of him, but clarifies that he did not mean during sex. Another deleted scene has Wallace accidentally flashing Scott again, and Scott saying it's fine because he's seen it.

It is worth mentioning that despite not liking or being friends with any other member of Scott's band, he still attends all their shows and vocally supports them. Even badmouthing their rival band as they were playing. Although this may just be Wallace's own snarkiness.

Comics

 * Scott is hinted at being bisexual in the comics, blushing when commenting on Lucas Lee's hotness while he and Ramona watched a movie of his. There is also a heart in his speech bubble later when he spoke to Lucas Lee in person. Ramona also jokingly told him to keep convincing her that he wasn't gay in response to his comment on Lucas Lee.
 * It's implied that something gay happened between him and Wallace to have led to them becoming roommates. Scott mentions that he did not want to talk about it, and when asked by Kim if it was a "really gay story", he vaguely answers with, "The story is somewhat gay, yes."
 * When asked if he was still living together with Wallace by Envy, Scott replies that they share a bed and it's totally hot.
 * Scott is shown to have worn 3 of Wallace's shirts (Black, blue flannel, and a pink polo). His socks are also Wallace's.
 * Scott and Wallace frequently go out for sushi together.
 * Wallace pays for most of, if not all of Scott's expenses.
 * Wallace ruffles Scott's hair and says that he looks hot as he always had when Scott was complaining about his hair growing out.
 * Wallace crashed at Scott's place when they were both drunk one time.
 * Wallace winked and called Scott baby when giving him a folder of information he collected of Gideon. His name also is signed on the front of the folder with a heart.
 * Wallace was one of the people that housed Scott after Ramona left him.

Movie

 * In a deleted scene, Scott calls himself "demi-gay" when Ramona calls him out for sharing a bed with Wallace since between him being straight and Wallace being gay, it should even out to only being 50% gay.
 * In another deleted scene - when flirting with Jimmy, Wallace brings up the fact that he sleeps with Scott to imply that he likes men.
 * All of Wallace's fuck buddies wake up in the bed with Scott in it, implying that they probably had sex next to him.
