Daisy (The Woman Who Fell to Earth)
From Tardis Wiki, the free Doctor Who reference
Daisy was the granddaughter of Dennis, a security guard at a Skylark construction site in Sheffield.
He was talking to 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. (TV: The Woman Who Fell to Earth)
