Howling:Jack's Memory

So, I was rewatching the first season of New Doctor Who, and when I got up to Jack's introduction, I was reminded of a plot point that I had completely forgotten about. When Jack was explaining why he left the Time Agency, he claimed that he had woken up one day missing two years of his memory, and he wasn't sure if he was a good person or not because of this. Now, with all the Torchwood episodes that deal with some dark secret from Jack's past catching up with him, from both before and after he gained his immortality, how did this never come up again, or did I miss something? Is this going to be a plot point in a future episode of Doctor Who, or did the writers just forget about it?Icecreamdif talk to me 04:41, October 6, 2011 (UTC)
