Well, in lieu of the "Face of Boe" thing, I did want to have the Doctor gaping at something!

Okay, that's a shallow reason. It was just lucky it played out that way; I actually wanted to show how Jack's grown dependant on Ianto, to the point where he'd turn away from the only real help he might have gotten. It was really fun playing with those different layers, as has been the case throughout the fic.

Thanks for reading and reviewing!
