Julian would be interested in hearing about them. Someday. He understands being so unilaterally despised--he'd feared it so terribly, and it had been a weight off his mind when everyone on the station had shrugged off the revelation of what he was and continued to take him for who he was. It had taken himself longer to realize that the world wasn't going to end just because everyone knew he was an Augment. It would be longer still before he stopped hating it.

But that is certainly a conversation for another time, if he breeches it at all.

"I'd ask how you'd gotten hurt in the first place, but I don't think I'd like the answer."

It's open-ended, if Khan would like to volunteer the information. Judging from his violent reaction to anyone wearing a uniform, his comment that the Enterprise had been severely damaged (if not outright destroyed, but he hadn't sounded certain of Captain Kirk's death, so he couldn't discount it being merely crippled), Julian was of the mind they had an impending explosion on their hands. He'd been against the Enterprise crew, Julian was sure of it--just as had happened in this timeline, eventually. He didn't know if Doctor McCoy was from before or after that point.

He just continues working, healing the fractured arm next. His job is not to judge--though admittedly he was sometimes rather bad about that--his job is to keep everyone in one piece.
