"So you're from my past or a version of my past. We might be from the same world then. I'm from a few years later. Maybe four? I've lost track a little bit in this world because the months were different when we came in and we've been here for a while."

He smiled at him.

"Yeah, you heard that right. Four years. Although I didn't age for one of those since I was taking a really, really long nap. In the dirt. Lucky for me, I got to go through that big ol' revolving door some of find us our way through. The Legion found a very, very complicated mad science way to revive me. It took three Brainiac 5's, Kal's chrysalis thing that revived him, and some time travel, but here I am."

Swinging his feet slightly on the edge of the roof, clearly happy to be there.
