Doctor Who: Joy to the World

 Following the first season of the 15th Doctor's adventures, there is of course the christmas special tradition.

 

And the special this time was called Joy to the World. 

The Doctor arrives at the Time Hotel, a place that has rooms to all area's in history, where he enlists the aid of Trev, one of the hotel employees.  He is investigating a man with a briefcase that is handcuffed to his hand.  But when a new person is tricked in taking the case from them, the previous carrier disintegrates, when Trev's Silurian manager arrives in the room of Joy Almondo in 2024 London, the Doctor following him.

 

With Joy now being the new carrier, the Doctor opens the case and finds a strange device inside.  He prevents Joy being disintegrated with the help of his future self, and the future Doctor takes Joy along.  The current Doctor takes a job at the hotel, working there for a year and befriending Anita, the hotel manager.  When he arrives at the point of his future self before, he takes Joy along to a point 65 million years in the past.  Opening the case they learn the contents are actually a star seed, a bomb that creates a new sun, created by the Villengard weapons company from the past season.

 

A T-rex eats the case, but he is contacted by Trev, who now had 65 million years time for his conscience that has been connected to the device, to figure out a way of contacting the Doctor.  That way they manage to find the case again, but as the Doctor wants to take the case outside Joy merges with the star seed.  She assures him the device has overcome the Villengard's programming, and that she will become a new star in the sky, becoming the Star of Bethlehem but not before advising the Doctor to find a friend to battle his inert loneliness.

 

A typical christmas episode, it connects to the previous season of the franchise, while laying the seeds for things to come in the upcoming one.  It's worth the watch, and best to do so to connect some dots...
