i'm sorry about the late response, i went to sleep last night before i could respond to this.
robb has always been a bit of a trouble maker, but within discrete limits. his father never fit into the expectations of his station because, in truth, he wasn't meant to inherit the dukedom. he didn't get into the right schools, and all that. so, he pushed robb to do all the things he didn't: go to eton, join the military, play sports. his father died in august 2016, and they'd been bickering over business things just before so he is conflicted about things. how does he handle that anxiety, you ask? alcohol, drugs, and women.
