Fyodor had a tiring day and he's overwhelmed from everything, so he's doing the same thing he already did many times when he feels not too well - Fyodor's forehead is rested against you and his icy, purple eyes are closed. Fyodor is basically using you like a little support human.

"Stand still."

Fyodor mumbles against you as he moves his head a little to rest it better on you.
