Episode 69

With a plot about an alien attempting to eradicate all life on Earth, "The Visitation" is a rather rote Doctor Who story. However, the serial is saved by Richard Mace (AKA Mr. Awesome), who Mike suggests might be related to another one-off companion from one of Tom Baker's most beloved stories. Then, in the two-part "Black Orchid," The Doctor is accused of murder, and a family secret prevents someone from corroborating The Doctor's alibi. Before all that, however, Chris Johnson drops by to deliver a segment that highlights the ups and downs of the recently ended Tom Baker era. (Said segment runs from 8:14 to 48:03.)
