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. Despite Scott's initial confusion at Wallace's forwardness, the latter continues to insert himself into Scott's life until they become friends (notably 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 Pine.

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 keeps Wallace's credit card in his wallet. His financial dependence has, in one instance, led to Wallace referring to Scott as "his bitch forever." Scott is frequently spotted wearing Wallace's clothes, although it only gets mentioned once.

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

Despite how much Wallace regularly teases Scott, he is shown to genuine care for his well-being and is quite protective of him. Though Wallace is generally levelheaded, he is shown to vehemently hate Envy Adams, Scott's cheating and ill-tempered ex-girlfriend. 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 (though this later turns out to not be entirely true, as Wallace had already signed a lease with his boyfriend Mobile by this point.) He continues to offer support and advice to Scott even after they stop becoming roommates and houses Scott for a while when his girlfriend Ramona briefly kicks him out of their apartment. It is implied that they shared a bed together again during this time despite no longer needing to, as Scott becomes flustered and says "I don't have to answer that" when Ramona asks if he slept on the couch or on Wallace's bed.

After Ramona breaks up with Scott, Wallace is once again there to support him. He makes breakfast for Scott and jokes about how he has "[Scott's] body to play with" in the temporary absence of Mobile. This is one of 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 jokingly suggestive texts directed at Scott to Ramona's phone, as Scott does not have his own. Ramona states that she feels like a personal secretary for all his "little mash notes".

Movie
Unlike the comics, Wallace is much more callous and forward about wanting Scott to move out and subsequently mature. Notably, Wallace is shown to let his hookups sleep in their bed along with Scott, who wakes up beside them and Wallace twice in the film. Scott was even shown to be between Other Scott (Wallace's boyfriend) 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 after Ramona breaks up with him. Scott seems to be somewhat reliant on this, begging for Wallace not to leave 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, Ramona's final evil ex, after Ramona leaves Scott for him. It is worth mentioning that despite seemingly not being close with any other member of Scott's band, he still attends all their shows and vocally supports them, even heckling a competing band as they were playing (although this may just be Wallace's general snarkiness.)

In one scene, Scott comes home and accidentally walks in on Wallace having sex, after which Wallace gently lets Scott know that he's being kicked out by saying "Scott, you know I love you, but I'm gonna need my own bed tonight." In the unused extended cut of this scene, Wallace offers to let Scott stay after he tells him that Ramona just broke up with him, giving him a sleeping mask and earmuffs to avoid having to see Wallace with his hookups. He follows this by telling Scott that he is thinking of him, quickly clarifying 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 one".

Comics

 * Scott is hinted at possibly being bisexual in the comics, blushing while commenting on action star Lucas Lee's hotness while he and Ramona are watching one of his movies. Ramona also jokingly tells him to keep convincing her that he wasn't gay in response to his comment on Lucas Lee. There is also a heart in his speech bubble later when he speaks to Lucas Lee in person, seemingly flustered at getting his attention.
 * It's implied that something "gay" happened between him and Wallace to have led to them becoming roommates. Scott mentions that he doesn't 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 with Wallace by Envy, Scott replies that they share a bed and it's "totally hot".
 * Scott is shown to have worn three of Wallace's shirts (a black t-shirt, a 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 the same as [he's] always looked; hot." when Scott was complaining about his hair growing out.
 * Wallace asks to crash Scott's place when they're both drunk, and the aftermath of this is never shown.
 * Wallace winks and calls 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.
 * Wallace was going to be nicknamed "Wally" in the original pitch for Scott Pilgrim. It can be inferred that Scott is the one who gave him that nickname, seeing as he calls Ramona "Rammy".

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 evens out to only being 50% gay each.
 * In another deleted scene, when flirting with Jimmy, Wallace brings up the fact that he sleeps with Scott to imply that he likes men, additionally asking if he thinks it's "hot".
 * All of Wallace's hookups wake up in the bed with Scott in it, implying that they possibly had sex next to him.
