"I am not sure how to explain it." Olivia wasn't even sure she wanted to. If she admitted who he was, then she was admitting he existed. If she did that, then she wasn't sure where her sanity had gone. It was a tumbling circle of doubt she really wasn't looking forward to getting into.
"You're a comic book hero, in movies, on tv. Superman, the guy from Kryp..ton? You're not real." She gave him a soft apologetic look.

She hadn't experienced it, but she certainly witnessed it.
