The Night Fury regards Henry's hand warily, at first, baring his teeth a little and narrowing his eyes. But as the hand gets closer, he relaxes. Henry's movements aren't urgent or aggressive, as such. He isn't sure why Henry wants to touch him, but it doesn't seem to be to cause the dragon injury. So, snorting, breath warm, the Night Fury leans forward just slightly and presses his snout gently to Henry's hand.

Just the once. Then he regards him warily, once again, and gets up to walk in a circle around him.
