4. What would their romance route look like? Would they be romancable?
Romanceable by male inquisitors only of course and may actually have humans locked out of the romance path, with Trevelyan being a noble, he straight up does not trust noble shems and will have to be talked into even regarding one as friendly, romance might just be off the table. (Also, tbh, I have a hard time imagining him with any Inquisitor but Olek now, but obvs he can be grabbed by at least one Inquisitor.)
7. What would be on their tombstone in the fade (what is their greatest fear)?
14. What nickname does Varric give them?
A friend of mine briefly RPed Varric over Skype with me and I have to say I’m forever fond of their Varric calling him ‘Jumpy’ because Tavi is indeed a nervous little creature.
16. What would the Fear Demon say to them in the Fade to try and discourage them?
Something about him not belonging here either, Tavi leaves people so readily as a way to avoid being rejected, with the Inquisition being something he’s sort of stuck with at least until Corypheus is gone, he’s put himself in a position of potentially being turned away before he can leave on his own.
