He did forget me, once. ( obviously it wasn't bad enough to be his worst memory, but. ) Mr. Mxyzptlk. . erased me? I guess? But Mom and Dad both forgot who I was for a little while.

( jon's very pointedly keeping his eyes away from damian's as he speaks, nose wrinkled in distaste. ) I made them remember because I was there, but this time--I'm here, and I don't know where they are. What if they forgot and I can't help them?

( being paranoid and pessimistic is damian's job, but--sometimes, he can't help it. jon is still only a child, and sometimes--he can't avoid negative thoughts. )
