Previously on shows Hiro's meeting with Arthur Petrelli, grabbing Hiro's head, the scream, etc. Mother blurts out, "What was THAT all about?!"
Later, by like five minutes, Hiro reveals he now thinks he's ten. And my mother asks what's going on, what happened.
"What do you think?!"
"His memories are gone! When and how did that happen???"
*bites his tongue*
