LONDON, Nov. 22 (UPI) -- Jenna Coleman has ended her run as Clara Oswald on TV's Doctor Who.
The beloved character died trying to save someone else's life in Saturday's episode of the popular science-fiction series, which stars Peter Capaldi as the titular time traveler.
Coleman, 29, announced during the summer she would be leaving the show after three seasons, but no details were released about how or when her character would exit.
Head writer Steven Moffat discussed Clara's death in a BBC video posted on Facebook Sunday under the caption: "Why did Clara have to face the raven? Steven explains Clara's courageous act."
"On one hand, [the Doctor] thinks: 'Great! Someone who will hold my hand and run with me, who understands why this is so exciting.' At the same time, he knows this is a young woman who is not like him and has become addicted to his lifestyle and as the Doctor says, she is just more breakable than he is."
Moffat went on to describe as "pretty impeccable" Clara's reason for making the decision that leads to her supreme sacrifice.
"She does what the Doctor, she reckons, would do," Moffat explained. "She does it out of heroism, out of compassion and because it's a good plan and because this is how she rolls now. This is what she does... Before Clara goes to her lonely death, her terrifying death, she tells the Doctor, 'No revenge.' Because she knows what he's like. Get the Doctor angry and he might blow something up. ... And that would dishonor her."
