This. I mean I know why the writers are having Julian act like this (inept writing) but it makes no sense otherwise. Julian used to genuinely give two shits about Sonny's threats and stood up to him. Suddenly, he's petrified of him. It would be one thing if Julian was worried about his reputation (not that he has much of one in town) being destroyed after he's worked hard to turn his life around, but instead it's more of Julian truly being afraid of Sonny.
As the rare person on the board who had no problem with Dev, this storyline turn with him is coming off so lame and annoying. I mean I kind of get them thinking they needed at least one of the teens to be a little more gray but this really did come out of nowhere. He turned Joss down with barely an explanation. It didn't seem like he was torn up about it or interested in her. Now, suddenly after one slight brush-off from her he's so desperate for her he's reading her journal, forging entries, and twirling his evil mustache behind Cameron's back. Like someone else said, they've gone from 0 to 100 here and it's especially stupid because the motivation is so slight. It was the same issue with Peter. I think because there was a lot of fan backlash, they decided to move him away from his Faison plotting and turn him basically into some Dudley Do-Right but when that wasn't working they decided the only way to fix it was have him plot a bunch of murders, including of a well-liked character. There's a middle ground they can't find or don't want to find.
