"Well met, mate. John Mitchell. Just Mitchell's fine indeed." He glanced down at the hand holding and then snorted at Jack. "Oh honestly, every new recruit?" he asked, and gave the pair a bit of a wave. "Welcome to Torchwood, Henry! Be seeing you, I'm sure! Got a bit of a mess to clean up. Should be back by dinner if this is working correctly." He opened up his own portal after a salute to Jack and slipped through the golden light of the vortex, which disappeared behind him.

Jack, thankfully, decided it was best, yet again, to explain.

"Vampire. More of a tea drinker than a blood drinker. We have a synthetic drink that keeps him from being an asshole." Yep. He'd met John Mitchell off the wagon. He really didn't mind the amazing sex that came with the blood lust but it was weird to sleep with your employees.
