I was thinking that it was a whole Westworld/ Star Trek holodeck thing. I'm so curious what's going to happen with Lucy and that egg. Anything could be coming out of it or it could be a dragon. I don't know. I can't wait to find out. I'm still hoping that at some point the Doctor will actually listen and hear the drumming in the Master's head.
Author's Response: I thought it would be interesting if a setting like that would be abandoned and just continue on its own xD Well, they got the egg from a dragon, so it's likely that a dragon will hatch from it. The big question ist just... How? ;D Hehe he, gods, I'm having too much fun with the creepy stuff
