Doctor Who Companion Profile: Peri
Perpugilliam Brown is an American college student on holiday with her stepfather when she nearly drowns and is saved by Turlough. Having been rescued and taken into the TARDIS to recover, Peri is aboard when it takes off, whisking her away with the Doctor, Turlough, and Kamelion to face off with the Master. Peri is studying botany in school, which comes in handy during her travels with the Doctor, and her parents are archeologists, giving her a solid background in that subject as well.
