Jayce was paying attention to the plant working in the corner of his eye when they kissed, don't worry. If it had changed he would notice. Besides, it is worth celebrating, and part of them being a couple is having a celebration of kisses as well as anything else. They can't have sex until Viktor is cured so there is nothing behind his affection other than love. He does think it's funny for the goggles to clack. They're such dorks.

Jayce lets Viktor get the sample because he is the one who knows exactly what he needs to look at. While Jayce does logically understand everything that is happening, even more so now with medical knowledge in his mind, this is very much Viktor's area that he's been invited into. With the occasional good idea added from him.

Looking at how it glows and how alive it looks, how alive Viktor is going to look, Jayce feels more confident than ever that anything was worth this. Whatever comes of his compromise, he feels no regret now. He would have done worse for him, in truth, and it was something they could live with, exactly as he promised. He smiles at Viktor, that determination such a great thing to see. He loves that Viktor is filled with fire instead of giving up. He wants to fight.

"It will. I know it. As soon as we're on the other side of this, you'll have to decide what you want to do to celebrate." Maybe finally go to the beach.
