Rosalind "Roz" Fielding is a friend of Holly Barton's from college. At first she appeared to be just a typical normal teenager but is later seen to be giving drugs to Holly. On Holly's 19th birthday Roz gives her some drugs in The Woolpack, when Holly's parents find out that Holly has been kicked out of college they confront her and tell Roz to leave. Holly is later banned from seeing or calling Roz. When Holly's father, John, accuses Holly of stealing ketamine, Holly stays at Roz's house. Holly later swaps the ketamine with Roz for cocaine. Holly later runs away from home and her parents John and Moira go and see Roz thinking that Holly is staying at her house again but Roz tells them that she has not heard from Holly.
