"I know," John says, because he does. He was there. He was the one doing it, he remembers. "I know and I'm sorry, okay? I'm sorry for holding a gun on you."

He leans back into the wall and takes a deep breath, lets it out slowly as he tries to steady himself.

"I'm fine now, I promise. Just had a weird moment."

A weird moment, which is a very mild way of admitting to losing months of memories for no immediately obvious reason.
