"So, you're boring." He didn't say it like an insult though, just like a fact. Warmbloods, coldbloods- it made it him think of reptiles and other animals. He supposed that wasn't too far off, either.

Nodding while he listened, he was more interested than he seemed. He was also doing his best to commit these little details to memory- they'd probably be important at some point or another. "How do you figure out what you are? Do the powers just happen on their own at first?"

He wasn't thinking there was anything actually different about how the blood types appeared, though he did glance at one of his hands, considering the possibilities. He wondered why the different 'types' had the names they did and what exactly determined their powers. What was he? Was he anything? Did it matter?

Grinning at the response to his rude but playful gesture, he nodded. He could appreciate someone who wasn't easily offended and who could, seemingly, put up with his bullshit. The next moment though, he was shaking his head as he caught the jacket, juggling the eye and hand in one, well, hand, so he could get it around his shoulders.

"You're not even gonna be a gentleman and drape it around my shoulders for me?" He appreciated it though, even if he was bad at saying 'thank you' and had already used up his one expression of gratitude for the day.
