The whole thing was going over Martha's head. She smiled and did relax, she'd just wait to be brought in on... whatever this was.
The smile was tentative as it all became clear as water. Captain Jack Harkness of the 133 Squadron, RAF; Huntsman; the man was sitting across from him, not looking a day older than the last time that Robert had seen him. The logic didn't compute. It didn't make sense at all. But if he was here in the future, well that didn't make any sense either. The two of them should have been old men. Truly
Hogan's smile only got bigger despite the many questions. "The good fight never ends, Jack. Just causes men to get tired and in need of rest, but never does it end." he stopped, watching him for a second. "The war's over, Jack. Papa Bear, Goldilocks, secret missions and transmissions," he shook his head.
"You look good. I haven't seen you since we sent Kinch home." He paused looking around. He knew the year. He knew the date. "And yet you don't look a day older..." Then again... neither did he. But had a very outlandish explanation. And it wasn't good genes.
