Am I really this forgetful?

So I wanted to revisit a handful of season 3 Forever Knight episodes for a story I'd like to finish aaaand the case is empty. Not a single DVD is in there. Hmmm. I check my season 1 & 2 cases and they too are empty. Curiouser and curiouser.

I have two of those large CD/DVD wallets from back in the day that I'd use when I'd come home from college and they're not in there either.

The only one in there is the first disc of season 1 which I had lent out to a former receptionist at work many moons ago. She was a big fan of vampire romance novels and Buffy so I lent her disc one and she lent me one of her books. I read her book (it was not good) but she eventually returned Forever Knight unwatched. Well that's the only disc I have.

I'm genuinely stumped. I know it's been a while since I've revisited the show, but it is rather hard to misplace several DVDs.
