[ Ferdinand almost always has a smile on his face, even if he's just being polite. But there's an uneasiness to his smile, for as relieved as he is to see his professor (not realizing that their recollections of events would differ greatly), he is likewise worried about what their presence here means. In his memories, the Adrestian Empire had united the entire continent of Fódlan, thanks in no small part to the professor's efforts. But there is still more important work to be done, and in this strange world with strange vehicles and mollusk-based entertainment, that work cannot be done.

He nods solemnly, a hand grasping at the professor's arm, careful not to grip too tightly. ]

I appreciate your concern, Professor. I am alright, but I must admit that my constitution doesn't lend itself to this method of travel.

[ The lack of color in his face probably makes that apparent. It had been a pretty smooth ride until very recently, but his discomfort is starting to show. ]

Forgive me for bringing this up at a time like this, but your hair... I distinctly remember that it had changed back to its original color. Then again, I'm not sure I can even trust my own memories right now.
