I thought so. [This Byleth might be harder to read, particularly with Sothis making his body language erratic and unnatural, but even still, Claude can tell when he's being pushed too hard. At least she acknowledges that and seems to be considering her options, but whether she'll act on it...]

I don't know what it will take for you to trust me, but I'm not prepared to leave him until you let him rest.

[And presumably she can't just get rid of him, if what she said about Byleth's restraints on her is true.]
