True! It appears that Finn may have gone back in time to right before the great nuclear war, which means the Lich may be responsible behind it. We might see Finn get a robot arm!

However, what if the Finn we saw at the end was Finn in the past, pre-Mushroom War, and that pre and post Finn meet each other?
