The funny thing about Liv's family is that they could have reconciled that very easily in like 1 episode.
In like 10 seconds! "Oh hey Olivia. Sorry we've ignored you for the last few years. We're doing okay. Bye." THE END.
Also Rahul's sketches are really good, and his handwriting is very tidy.
Yeah, I guess I can buy that explanation. It just seemed weird as I was binging the rest of the season and trying to reconcile their relationship with the previous ones.
Blaine suddenly having remorse about his father seemed believable to me. Poor relationships with fathers are rarely so far gone that they can't be reconciled. Blaine probably stepped back and went "Wait a second... I'm responsible for literally every bad thing in this town, and my father is actually a half decent person now if you ignore the zombie zealotry (but that's my fault anyways). And he's going to charge off on a horse to his certain demise." Blaine never seemed so bitter that he wouldn't forgive his father, if his father started treating him decently. I do think the weekly dinners with his father was something Blaine had secretly wanted for a really long time, and that started to mess with him a bit. He's never known his father to be supportive or think highly of him, and suddenly he's being bombarded by that. And then he cons his father with the brain snow and it hits him like a bag of bricks right before the end.
Then he'll shrug it off and go back to being Blaine because Major just wrote him a blank check, and Blaine needs some cold hard cash to wallow in for a while. I also find this fairly believable, because people often have moments of clarity then go right back to what they were doing like nothing happened.
