Titus has no trouble catching up to Sulannus, as she has been in no real hurry to get far. She stops when he accosts her, though doesn't turn around to face him. When he's done, she still doesn't turn, but does reply.
"This isn't about her," she snaps...though she immediately seems to regret it a little, since her tone softens a bit afterward. "It's about the fact that despite everything I've done for you, he still doesn't trust me. I've risked my life to help you fight, I've contributed what little funds I had left, I've followed you halfway through the human world, given up any chance at learning magic any time soon, been humiliated, insulted, looked down on...and that's just since we met! None of you have any idea what I've given up just to be here in the first place!"
She cuts herself off there and takes a deep breath, then reaches up with her hands to do something with her face that Titus can't see. When she talks again, her tone is composed.
"I don't blame any of you for any of that. I made my choices, and I stand by them. It would just be nice if you all could repay the trust I've shown you in kind."
