Tough call. Flash is clearly struggling to come to grips with his romantic history. The fact that the two (three?) girls he’s had feelings for are emotionally unavailable and since Wallflower is so reserved, all she’d have to do is listen to him every now and again to get his attention. Not to mention that Wallflower is practically starved for affection, she’d probably be okay with “the most popular boy in school” venting to her. I can’t say it would
start as a particularly healthy relationship, but it’s definitely within the realm of possibility.
As for Sunset, she strikes me as someone that isn’t particularly interested in romance. She’d probably go on a few dates but wouldn’t fully commit to a relationship. Should she ever become pregnant, she may end up accepting help from the father but not be part of a nuclear family.
