Let's be honest here: Kai had no idea what his actual temperature was either. But he felt okay. Therefore he had a whole lot of confidence in something that very well could have been burning up. Let's all be pleasantly surprised when it actually worked out in his favor this time. It was indeed just mildly warmer than it should have been.

Warm enough that the feeling of Shinji's hand was pleasantly cool. That was nice. He leaned into it, just a little bit.

"See?" There it was again, the ballsy confidence.
