Yeah, I don't know about Lauren, but if that was me I'd also be unhappy that someone just dropped more work on my lap out of nowhere at 3 in the morning and that another asshole just put the kid who I've been helping (and who just got his family reunited again) in jail. I don't know anyone happy at 3 in the morning (Veronica is hte excepction, not the rule).
And the more we see of Katie the less... malicious she seems? Like maybe this is me being blinded by pussy, but she seems vastly different than when the MC first met her, more chill at least. Who knows, maybe she did just wanted to get smashed by MC and just had the awful timing of trying to jump his bones right when he was the most on edge about Charles.
