So, I found a short little CoE fixit (who doesn't like bringing Ianto back to life?).
Third Chances is just 5 shortish chapters. It's a fic off ff.net by MegK1978 and is from November/December 2010.
Summary: On the morning of Day 5, a woman visits the makeshift morgue to see the body of her cousin, Ianto Jones. Just one problem: Ianto doesn't HAVE a cousin named "Rebecca Jones".
Fic is here!
