Fic is (hopefully) going to be good for that - but we shouldn't have to do so much work to make it work, right?
Before this season I would have said that I firmly support making the audience work for it . . . but there are limits, and I think Moff found them /o\

I'm holding out some hope that, as we know all three Ponds will be making further appearances next year, some of the gaps will get filled in retroactively?
