To be fair, John hadn't known what his own actions were going forward. John was truly just flying by his whims, as he would do. Though when he saw Kitty, his mind was on her and her alone. His fury was taming and that did annoy John, considering he wanted to be angry. So now it was turning into anger for angers sake, and that was pointless.
Well, yes. It was her who caused the catalyst for John, but even John in his now slightly less infuriated mind could see he was particularly over reacting. "Equal parts." John compromised. His fury was his own, which was not her doing. She could own her hiding that information, but he'd never let her take responsibility.
Though the kiss. Wow this kiss. It was fierce and desiring. Despire all his rage, he still had these feelings for Kitty, and the kiss would show that. Pulling her firmly against him he deepened the kiss to show just how much he still cared despite what happened just earlier. Just because silly mistakes, didn't mean you let the world burn. Well, you did if you were Pyro.
Breaking the kiss with a gasp, he was winded a little from that, and even desired more. "We're going to be fine." He told her again confidently, before dipping down and pressing his mouth to hers again in a much more wanting kiss than previously.
