Resolution

No more Christmas specials, this is a new years episode.

A lone dalek invades Earth in the past and is defeated beings buried in 3 parts across the globe until the part in England is found and it is reformed.

Two plots, Ryan's dad returns and gives Ryan and Graham character progression. While that happens a dalek is being built out of scraps, it's obviously defeated. We also discover UNIT doesn't exist anymore, because the government sucks and didn't provide enough funds which makes sense seeing as many UNIT HQs have been destroyed.
