Words fail me as to how happy was when this came up on my flist this morning!

Don't tell Jack or Ianto, but I think I may love Nicholas even more than I love them.

And I had this most wicked thought - when Nicholas has finished traveling with the Doctor this season, how hysterical would it be to drop him in Gene Hunt's lap in Life on Mars? He at least would be able to offer some time-traveling advice/consolation to poor Sam, letting him know he's not really gone insane.
