Well, I don't know.. Shrug.. Beside, Josh's character wasn't my fav on Fringe since I get sometimes bored w/ his scenes since I feel like he wasn't great actor on the show, but I only like him when he's w/ Olivia or Walter, but if he's only, I sometimes skip his scene..
But it get better for two of them, but like you said, it's all depend on people..
