This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: Sibling Rivalry

This is a fairly simple story, but a fun one which is really what this whole set is supposed to be. My only complaint is that there aren't enough scenes with the Doctor, Constance and Flip all together but the story makes up for it by being largely focused on Flip. The Sontarans didn't add much personally but other than that this was great.
