Right, yes, because Callie and her educational Christmas opportunity were entirely behind the Doctor's begrudging interest in this museum experience, absolutely. Try to keep up, Ianto. "It isn't, but it should be," is the Doctor's assessment. "It's anthropologically significant. And there's usually candy." What else, what else. That's probably enough. "The fact that it sounds bonkers is likely in our favour. There'll be loads of aliens, no one will bat an eye." Or any other alien sense organs. Probably there's aliens? But humans would be fine too. The Doctor is warming to the idea, and with good reason. What could be safer than Christmas? Disclaimers aside. Probably just like a roller coaster park. Though maybe they should have Ianto sign a waiver, just in case. "She's got a lot of Christmases to make up for." Maybe they'll do Christmas for a week. Maybe longer. It would strain his Christmas tolerance, but the sacrifice just makes it more meaningful. Isn't that what it's all about? "We can start there." So that's settled.
