Rahul (The Woman Who Fell to Earth)

Rahul was a man who lost his sister, Asha Chandra, in mysterious circumstances. He sought to find out what had happened to her.

Spending years keeping up with alien conspiracy theories and monitoring energy readings in Sheffield, he eventually found the pod again that emitted the creature which stole his sister. After paying his van driver to help deliver the pod to his warehouse, he spent the night waiting for it to open. When it did, he confronted the creature inside, Tzim-Sha, demanding to know what he did with his sister. The alien advanced on him, stating he would never know before freezing him to death.

The Thirteenth Doctor later found his coprse, along with Grace, Graham, Ryan and Yas. (TV: The Woman Who Fell to Earth)
