"I-" Jack's face falls. He does as requested and lowers his voice. There is something very very wrong here, but he can't figure out what it is if they all get into trouble and get kicked out.

"I'm very sorry. You- you look just like...someone I'm looking for." Well, didn't he just say it? Someone he thought was dead. He briefly looks away, regretful.

Jack appears to regain his composure. "Captain Jack Harkness. If we keep it down, can we stay back here? I'm not with the unit up front. We're mostly civilian contractors, they're giving us a hard time."

He is still giving the woman a very searching look, as if looking for differences between her and Kalki, but not finding them. The wheels of his mind are trying to turn quickly, he thinks he has a suspicion about what is going on here...but that's literally not possible.
