1. How does your character feel about personal space?
Trowa's played so many roles that he can't really outwardly reject people in his personal space, because in the past, that could have ruined his farce. In a public sphere, he is indifferent to people sitting too close to him or bumping him on the sidewalk. In more personal matters, he is not a fan of close contact and while he probably won't shove anyone off, (except in extreme circumstance), he will not reciprocate. It's only the select few that he has affections for, that he'll behave more or less like a big housecat. They shouldn't be surprise to find long legs across their lap, or a head on their shoulder.
2. What is your character’s dream career?
Trowa has absolutely no idea at this point. He kind of though he'd be a solider/mercenary until he died. ((To be fair, I can see him getting into veterinary science or some kind of mechanical engineering with the right push))
8. Describe how your character deals with failed or failing relationships, whether familial, platonic, romantic, sexual, or otherwise.
Mr. King-of-the-Road here always has one foot out of the door, but while he'll tell himself (and anyone else who's stupid enough to ask) that he's indifferent to people's comings and goings, it always hits him on a very deep level. He's had very few real relationships in his life and a whole lot of abandonment. He's hesitant to form attachments, but when he does they are unfortunately earnest, so when they break apart, the only way he can deal with things is to bury that piece of himself away and never touch it again. Anyone who pushes him out of their life should be prepared to never see him again. (He'll make himself impossible to find).
11. Just for fun: If your character was the protagonist of a fantasy RPG, what would their class be?
