Ahaa. Well. I have not rewatched that episode and forgot that he mentioned it to the Doctor.

ALSO I have not watched Torchwood (though I knew James Marsters was on it, so I just googled his character). I'll wiki myself up to speed as need be.

I think I find it easier to believe that Jack would just be discovering demons/magic/vamps/etc than the Doctor. But, then again, the ones where the Doctor is like 'oh yeah vampires exist NBD' sort of rub me the wrong way.

I have to go out for a liiiittle bit but plan to spend most of my day reading, so I'll be back soon :)
