Companion Exits

Companions come and go - sometimes sad, sometimes not. However, the way they leave the TARDIS and the Doctor can be controversial at times. Jessica and Phillip look at how all of the nuWho companions have left and whether it made sense. They also connect them to "classic" companion exits to see if there are any patterns to how the TARDIS journey ends. 

In their look into the TARDIS library, they travel to the 5th Doctor adventure "Earthshock" for a rare companion death. 

Which companion's exit is the most memorable?
