Len hadn't gone on the mission to be a hero. He hadn't intended to die on that mission as well, to feel like he was part of something bigger, to sacrifice himself to save his friends. His team.

"Can't do that," he bites out. "Falling into time, into the time stream itself, I think it changed me. I need to know how. I need to know what it did to me." If he's a danger to anyone else. More than just his typical need to stay in control and be hyper-aware of everything around him, Len has to know.

"I have to know." He has to know before he can really talk to Mick, reach out to his old friend and partner again.
