Twice Upon a Time is the 2017 Christmas Special and the last episodes for Peter Capaldini and our Glorious Overlord Steven Moffat. It will most likely be GOAT and the last good thing in Doctor Who before the 2018 Cancellation. This page has been rendered useless, as another page was made a few minutes before this one, and is much more detailed. However, due to this wiki's nature, this page is now officially deemed canon, and will remain as such. Still not as canon as a certain other page though.
