Summary
This was a horrible idea. His second thoughts had been right. Mark thought distantly biting his lip until he tasted iron.
It hurt, it hurt, it hurt.
His arm was decidedly bend the wrong way, white peaking out from his flesh. It hurt so bad. Mark could feel his eyes stinging.
And though it was something big boys didn’t do — and though Mark was very much a big boy — he started to cry.
Aka Mark turns nine. He’s a big boy now… so why can he still not fly?

"What did I- He do?" Mark asked cautiously.
Cecil narrowed his eyes. "I think a better question is... What are you going to do?"
Or:
During his fight with Angstrom, Mark is sent to a nearly identical world where he is not such a welcome sight. -

Summary
“Mark, do you think those dreams are real?”
Yes. “No.”
“Yeah, they aren’t. They’re just dreams, kid—intrusive thoughts. Everybody gets them,” he stated as if it were that simple, “That doesn’t make you a bad person, and you wouldn’t replicate anything you saw in your dreams either, I’m sure of it. Your reaction right now says it all—you can barely even stomach the thought of it."
5 times Mark dreams of memories that aren’t his own and 1 time someone else dreams his.
