Lea hadn't been worried about a potential attack, really. It had more been just an instinctive reaction to move out of the way to avoid a potential collision with a quick moving object. But there was no way for either of them to know the other's thoughts on the matter just then.

In any case the book was closed, and Prompto took a seat on the couch. Though he didn't open up his wings, instead seeming to try and press them in even closer. Given the body language, Lea suspected that whatever had Prompto so freaked out probably had something to do with them. Which, he supposed, was understandable. Wings, by their very nature, were relatively delicate and probably full of nerve endings; a good spot to attack if you wanted to hurt any creature who had them. (A part of him kind of hated that he knew that.)

Lea pulled over the chair that he'd been sitting in before and set it so that it was facing Prompto before sitting back down. Not quite in arms reach but still close enough that they could talk quietly. He doubted that Prompto wanted this conversation to attract attention. "OK," he said his tone still calm. "Now, what's an 'MT'? Given your reaction, I'm guessing it's not a good thing."
