Doctor Who episode 208: The Wheel in Space – Episode 5 (25/5/1968)
The most impactful scene in this episode is the death of Gemma Corwyn. It repays the effort writer David Whitaker has put into making her a more rounded character than the normal base-under-siege fodder. Her calm bravery as she insists on delivering her final message to save the Wheel, fully aware of the approaching Cybermen, and the Doctor’s desperate reaction to seeing her gunned down, is a powerful moment. Season Five has seen several stories placing women in key roles: Miss Garrett, Astrid, Anne Travers, Megan Jones, but they’re usually the ones left to pick up the pieces at the end of the story. Gemma seems to be set up to play this part, especially given Bennett’s nervous breakdown, which makes her heroic sacrifice even more shocking.
