the true pinnacle of his career. that definitely shot him up a lot more notoriety wise from being somewhat stagnant after into the wild, where he was known as kind of a troublemaking bad boy and was pretty fucked up behind the scenes BUT that's sort of transitioned into him being seen as the unpredictable, rough & tumble all american boy of sorts (per his pr team's angle) because in reality he talks a lot of shit, can be loud, says whatever he's thinking and can get in trouble because all of that. buuuut i think around blue valentine he would've been a mostly good boy even in the press BUT if we want a progression of fun i could totally see him giving her shit in the beginning, with her family history & glee connection, but like you said it was a lot of improv and a pretty short shoot if i'm remembering and because of that/because he felt relaxed with the material in the film he would have probably helped round up the crew to come out for drinks and maybe if she ended up snapping back at him during some point because of the shit he was giving her he would've seen it as a whoa moment, and that could've led to a night out where they would end up building that rapport and he wasn't quite as much of a dick?
