In the Hub
When the little group comes into the Hub through the cog door, Jack is mostly expecting to see Ianto returning from upstairs. He isn't at all expecting to see Alice there with him, though the sight of a pretty blonde isn't all that unusual. It's Torchwood, after all; they seem to attract pretty when they aren't attracting deadly smelly ugliness.
Looking to Jenny, he puts on his best bright smile. "Heeey, who do we have here?"
