[Hythlodaeus steps onto the offered hand with a smile, and as the hand rises up he shows no sign of fear. As he's demonstrated before, if he fell he could simply teleport to safety. He doesn't think Reiner would drop him, anyway.

The first thing he does is observe Reiner's face, humming as he reaches out to press his hand lightly on his armoured cheek. He knocks a little, testing the hardness, before nodding. It's not like bone. It's also extremely tough. He highly doubts anything he did could break through it actually, though he also doesn't intend to try, either. Either way, he's clearly delighted by the whole thing.]

Wonderful. My thanks for indulging me. Has anything ever broken through these armoured plates?

[He looks up- Reiner can nod or shake his head, either way he wonders what kind of force would be needed to do such a thing.]
