The Scriptwriter

The Scriptwriter wrote two "crummy" movies about the adventures of Dr. Who, Susan, Ian Chesterton and Barbara, who possessed some independent existence as sentient fictional characters. Partway through his writing a third film, Susan finally realised that the Scriptwriter was her and all the others' "true enemy"; somehow reaching beyond her own fictionality, she staked the Scriptwriter through the heart, like a vampire, putting an end to the franchise and thus freeing herself.
