Nat shrugged. "I don't think you're gonna win that argument, Tony. I mean, the alien did just basically kill herself to get the Gem off this planet. You know how the Captain gets when his friends are on the line."
Sam glanced at the spy, his brow furrowed. "You know something about this Doctor?"
A smirk appeared in the corner of her lips. "Rumors, mostly. Never saw this face before, but there's a long line of accomplishments attributed to someone called 'The Doctor'. Mostly involving alien contact and saving the planet. Ties to Torchwood. Stories crop up all over history, as far back as Pompeii. Cap says she's a time traveler. So who knows?"
Sam looked back at the doorway the Captain and his friend had just exited through. "The Doctor does. Maybe Cap, too."
