Gwen was carefully watching Jack, Martha, and the Doctor. She understood perfectly well why Jack would be upset with the Doctor, but not vice versa. She set down her beer, stood up, and promptly slammed both of her hands down on the table to get everyone's attention.
"Now. If you boys are done glaring at each other and arguing, let's get back to the point of this. Doctor, We've got full medical records on what's happened to Martha since Jack rescued her from the Skrulls. It's standard Torchwood procedure that any time something happens to one of us, our medical files get updated. Bottom line is that Martha can suddenly heal really fast. Is this something that will harm her in the long run? And if so, can it be reversed?"
Jack smiled proudly as he let Gwen take the lead, marveling once again at how amazing a leader she'd become over the years. Heart, compassion, guts, and a fiery Welsh temper to go with it. That was his girl... his best friend and Second-in-Command.
"I can give you full access to the Torchwood computer systems. If you want, you can just access it from inside of the TARDIS. I don't think what's happening to her has anything to do with me. My daughter and grandson are both normal... not even human plus. If anything, they might have some 51st century pheromones, but that's about it." Jack ate a bite of his slice of pizza and leaned back in the chair, reigning in his temper and trying to stay calm. If the Doctor wanted to have a go at him, they could do it later.
"And before you start in on Jack for letting Martha get hurt, I saw the CCTV footage. He not only stopped the Weevil, but Jack also killed himself so he could recover faster and save her," Gwen pointed out. There might be fire in the Doctor's eyes, but there was plenty of the same in Gwen's as well.
