"I spoke to you. Just not the way you wanted." Said pointedly - as it was responding in kind to what Kylo had done. He was rude, so Iorveth was rude. He stopped being rude, Iorveth stopped being rude. Which is actually a better response than most humans who even breathe near him get. Ren's benefiting from the fact Iorveth is inescapably surrounded by mostly humans at the moment, which means making excess trouble would be to his extreme disadvantage. For now.

Grabbing at the arm, he uses it to give a small salute of thanks, then repeats the pattern - stabs it into the ice, wiggles it some to make sure it's solidly in there, then jump the next step up. The process repeats on the next. Hopefully they'll have enough in the way of scalpel arms to get up there. Otherwise, they'll have to start finding other things to improvise with.

"You don't seem to cast as the other mages do here." He comments, watching the next scalpel float to him. No muttering of words or odd symbols or wands. A very un-mage-like mage.
