@Bibliophile20: I think Bart isn't revealing the truth to those around him because if he does, it might completely screw up the timeline. If you were from the future with the knowledge of everything that's going to happen to the people around you, wouldn't you rather keep it to yourself and not mess around with it due to the risk of things going horribly wrong? Yes, Bart being there is already changing the timeline, but I think his philosophy is that the less he tells, the more stable the universe will be. A lot can change with a tiny piece of information. Hell, Bart just BEING there saved Barry's life. Imagine how things would change if he tells everyone what happens in the next 40 years.

That's just my reasoning behind it though - we'll just have to wait and see where this goes.
