Imagine;

Joe being woken up by Cody at night. He asks what's wrong and Cody's half crying, telling him about a nightmare, about turning into someone he's not, hurting others, killing people, everyone turning against him.

"I don't wanna be that person, Joe!"

Joe hugs him and talks to him until he calms down, but Cody is still crying slightly. Then he says;

'I remember I used to do this for you when we were 8. I was 10 minutes younger, but I acted like the older one. You'd wake me up at night, scared because of a dream you had. I'd talk to you, tell you it was okay until you went back to sleep...'

He then starts sobbing a bit more.

"It's funny how time has changed those roles..."
