In this week’s episode, we meet Delta, who is being chased by some dude and his Bannermen. Together with the Doctor and Mel, they take a bus to the late 50s, where her egg hatches and she has a green baby who grows up to be a less green baby that is able to make two different kinds of sounds. Eventually, the man who has the bannermen sets a trap on the Tardis that he manages to walk into himself. The end.
