Happy Birthday John and Alex: The Flirty Styles of Captain Jack and River Song

Both Captain Jack and River are damn good at what they do: getting The Doctor, and his companions all flustered, but they do it a little differently.

With that face, he doesn't need anything more than a grin and an introduction. There's nothing sexier than a man who dives right in.

When she's not trying to murder The Doctor, she's busy flirting with him. Unfortunately, they meet out of order, so she can never know how much flirting is appropriate. *spoilers*

Thank God she has such a boopable nose, beacuse:

Once she knows where she stands, the flirting comes out in all force. And all that in front of her parents... How shameless.

John Barrowman takes his duties as the biggest flirt in the universe seriously. He takes it all the way to Comic-Con.

The Doctor of New-Who has been traditionally non-violent, that is, until he met River. Now, there's nothing sexier than a woman with a gun. Even Jack couldn't get him to put down his banana.

The logistics involved in what he's hinting at seem daunting at best, but we know Captain Jack can handle any position we through at him.

Who can tell who's the bigger flirt? We definitely can't, all we can hope is that some of that sugar comes our way.
