Is this a real fic?

[snufflesdbear]

This could either be a fic search, or a passing comment I read somewhere, but not a real fic :-) I sound like such a goober.
Ianto *is* The Doctor. A later regeneration, come back in time to be with Jack (I think).
See, very fuzzy details. That's why I am not sure it's real.
THANKS! in advance, in case I can not get online long enough to say thanks, assuming it's found/real/not a figment of my poor burned imagination.
