I liked the laugh, it was hilarious. Yeah, no idea why Jack left them behind but I don't believe they'll die so I'm okay with it. I'm not through Old Who either and I haven't seen the SJC spinoff but I got it as well. I know a lot of people don't like or are sick of the Daleks but I can't help LOVING them and all they represent to the Doctor. I'm all about the Time Lord history and pain.

But yeah, if they're bringing everyone back, they might as well bring back the Master! I even for a second thought the Doctor would regenerate into him omgIwanthimbacksomuch. In the end, you're right, the screens all around the world would explode if that happened.
