Kirsty (Hostile Environment)
From Tardis Wiki, the free Doctor Who reference
Kirsty was a homeless woman who lived in Cardiff. Her mother died from breast cancer, a disease that Kirsty promised her mother that she would never get.
Living on the streets, Kirsty befriended Tyler Steele, although she stole his money several times. The two fled the city for Troed-y-Rhiw, trying to escape Oblation's Street Guardians, but they were caught in Treforest and ordered back. She found a lump on her breast and, after Tyler was allowed to live in the Hub, called out for him on Roald Dahl Plass. He chose not to see her. (AUDIO: Hostile Environment)
