Dennis (The Woman Who Fell to Earth)

Dennis was a security guard at a Skylark construction site in Sheffield. He was talking to his granddaughter Daisy via his iPad when Tim Shaw appeared outside.

Cutting the call, Dennis proceeded to confront the Stenza only for Tim Shaw to kill him by freezing him to death and taking one of his teeth. His corpse was later found by the Thirteenth Doctor. (TV: The Woman Who Fell to Earth)
