Wyatt understands as he watches Tim, it's a feeling he has had ever since the incident. Then he cheers uup a bit, "We can't change was has come, or rather even if we could we probably shouldn't." he may have thought about it a couple of times, "But we can do all we can to be prepared so that if something like that does happen again we can do more." he knows how powerful Tim is or at least has an idea so he figures he knows what Tim is thinking, and it actually helps him hearing it said out loud.
