There is an explosion:

Oh my God!

Greetings Human! I am Roberto, Robot for the Future!

Oh my God!

You are understandably confused.

Oh my God! You've come back in time to kill me because I'm the next Hitler!

Nonsense! I've been sent back in time to kill no one!

But my name really is Hitler!

Irrelevant!

And I keep having these unwholesome thoughts.

Mine is not the place to judge you, mortal.

But, there has to be something wrong with me for having them, right? Something so wrong that a time traveling robot has to come back to stop me from doing it. I mean, no one normal would have these thoughts, would they?

Hitler, you are 15. Nothing you do will ever seem normal to you.
