I can definitely see Jack retconning Owen and other interview candidates

So can Owen. Ianto I think wouldn't suspect it, neither would Tosh, Gwen would start defending Jack from the accusation, then remember he retconned her when first they met and admit Jack is just the type of practical bastard to do this.

Also? It fits with the pattern. Of Jack doing things that have been done to him - taking away memories, running away without explanation for the left behind, and now resurrecting.

I love the bit about Owen initially thinking his own tears were Jack's blood.

I'm glad that worked, because I was a bit uncertain whether or not to use it, whether it wasn't too much, but it just wanted to be written.

And thanks for the feedback! See, this is why their relationship is the one between Torchwood members I find most interesting. (Which doesn't mean I am not invested in the others as well, now that the writing has improved so much!)
