On one hand, that's a problem, but on the other hand - if our Monica had learn her lessons from what happened, the game would have been over long ago. As for my preferences, I wish we had a real choice from the very beginning what Monica should do - learn lessons by becoming smarter and more cunning, or keep stepping on the same rake, falling deeper and deeper into dependence on the people around her. Yes, I realise that such a separation would complicate the whole game, because the developer would have to create separate story branches for two different Monica's going down different paths. But that didn't happen (for one reason or another), so it's worth basing it on the current game reality.
However, all is not lost yet and if in the finale of episode 4 Monica emerges victorious, learns her life lessons and stops being a bitch, I'll be glad for such good ending (as I'll be glad for bad endings like sending her to the farm, which undoubtedly should be too).
As for Biff, on the contrary, I'm insanely glad I won't have to look at that nasty annoying face. I hope it's forever, but if there's suddenly a scene where the guard gives him a kick up the arse and Biff falls down the stairs, losing his teeth on the way, I'll even pay for it.
Not
if, but
when. I'm sure there will be such a scene because Victoria is an honest girl and wouldn't lie to Melanie about such things.
