(first time poster here, nice meeting ya'll
)
On my first playthrough with a Trevelyan manquisitor archer, he bro-ed up with Sera. Was originally going to romance her then she turned him down, but he eventually got together with Lady Scribbles after that. They remained bros for life, dissing snotty nobles, breech/breach raiding, helping refugees and making cookies. No raisins. Aside from her, theres Bull, Dorian, Blackwall.
Second playthrogh, I bromanced almost everyone on my Cadash femquisitor warrior, eventually riding the bull along the way. 
On my recent playthrough, with a dalish dual wielding femquis, everyones hatin' on her guts, except for Vivi. Was kinda surprised how concerned she was at skyhold after haven. "Dear you look dreadful, let me have a look at you." I'm fine, mum.
