10 Best Doctor Who Companion Departures (And 5 Worst)

4 JO GRANT

Leaves in: “The Green Death”

The departure of a companion was often a rushed affair. It was rare that it would be seen to affect the Doctor at all. Arguably, Jo leaving at the end of The Green Death is the first time since Susan’s departure that he’s clearly truly upset. And with good reason…

The third Doctor and Jo’s relationship is largely paternal. But, in leaving him for young, hip scientist Cliff, it’s hard not to think that the Doctor isn’t just sad to be losing a friend – he’s also jealous. He’s been binned off for a younger man! (And one who even has a certain Doctor-ish quality to him.) You only have to look at the poor love’s expression as he drives away in Bessie to see his hearts break once again.
