Oh, that's not the end of the story, Karen. That's just the goddamn beginning.

[ his biggest regret, what a question. he scoffs, though it's not directed at her in any way. ]

I didn't let her go, I guess. I don't know, I haven't gotten to that part yet myself, but- Well, I already told you about the Nauvoo and flyin' Eros into Venus. From what they tell me Julie was with me. I know it sounds impossible, but when it comes to this protomolecule shit? Real world rules don't apply. You know, like physics and shit.

[ he scratches at his face and leans back a little. ]

I guess my biggest regret was getting cancer - could've done without that part. And if we hadn't stopped for that radiation detour Semi would probably still be alive.

Regrets don't get you nothin' but more regrets though, do they?
