You know everyone is hating lily but i believe with the whole "even some monsters can atone" talk with AJ was suppose to parallel Lily and even though she did some shit she could be forgiven if she tries to make it right. But this could just be a theory and im wrong.
if we do get episodes 3 + 4, I do think we will at least have the opportunity to get Lilly to redeem herself. I want to call attention to this amazing meta that someone on Reddit posted about Lilly that I really do think describes her character perfectly:
It has been confirmed (I think by Lilly’s VA, but also by Larry’s general demeanor and treatment of his daughter in the game) that Lilly was abused by her father. I think her consistent defense of Larry throughout season 1 was because she had to adapt and always be on his side so she doesn’t get hurt. I think Lilly’s behavior here in season 4 is also a result of her having to adopt and be seen as a tough bitch so she doesn’t get hurt. I genuinely think Lilly isn’t an intrinsically bad person, but gets caught up with the worst people and has to focus on surviving rather than doing the right thing. I think that AJ’s atonement will serve as a parallel to Lilly’s atonement. I mean, AJ and Lilly both shot members of their respective groups (though under completely different circumstances and in different states of mind - AJ is still a KID after all while Lilly’s a grown ass woman). Telltale is definitely setting up a parallel between them, but I think Lilly’s redemption will be optional.
