A lovely Idea for a Minisode, with some great Acting Moments for Piper, her Reaction to the Doctor changing is easily the Highlight in this Story. On the other hand, it's nice to see Tennant so early on, trying to figure out how he wants to play the Part.

As its own Thing, it's fairly solid, honestly, but Part of me wonders if I liked this part much more if it was in 'The Christmas Invasion'.

Solid stuff really.
