Man, I wish you didn't have to screw over the Dad for the Twins' questline... He's so cool and chill, I actually really like him. Usually, the dads in these kinds of games are either generic deadbeats or sleazebag assholes; and that's if they even exist in the first place. The Dad here is such a breath of fresh air, honestly.
I'd feel bad about taking Linda away from him if I didn't think he probably enjoys the cold and abusive process of a failing marriage. The threesome almost made up for it, but I still plan to redo the questline depending on how things play out. Doesn't seem he has it too hard, at least.
