Oh, how I wish someone would write the meeting between Twelve and Gwen! Honestly, I think the only Doctor who wouldn't put Gwen in her place would be Ten because he let Rose wrap him around her finger. I'd love to see River come down hard on Gwen too!

Jack himself should have put Gwen in her place though, right from the start he let her get away with things he wouldn't have tolerated from anyone else. It made no sense.
