There's a prequel for this year's Christmas special -- but it won't embed so click the link if you are curious.
- lol I've written this fic!
- The idea of him calling Amy for help and then realizing Amy doesn't travel with him anymore is kind of sad, like Ten talking to himself in PIC, but I think it's a great example of why this 200-year-gap thing is fucking stupid. After TWO HUNDRED YEARS he hasn't wrapped his head around it yet? This would be more believable if the time was much much shorter.
- I have no idea what this has to do with the plot for the Christmas special. I suspect the answer is "nothing", based on the importance of the previous prequels. Like that one where Amy had emotions about her baby.
