well lilly is definitely not a popular character and her fans are definitely in the minority. I was definitely pissed when she shot Carley but she was losing it and if she was more sane at the time it would never have happened.
I don't like her but it doesn't mean that she can't bring an interesting dynamic or interactions with the new cast in season 2. It could be interesting and bring some tense drama in the game.
One thing's for sure, there's no way i'm letting the protagonist I play trust her lol
