Rayne Hart is a young girl from Holby.
On 8 September 2007, a bomb exploded on a coach, resulting in Rayne and her mother Wendi being injured. Junior doctor Toby De Silva managed to retrieve Rayne from a collapsed building, but her father Rob grabbed her and pushed Toby into the coach, believing that he was attempting to abduct her. Later that day, Toby found a hysterical Rob cradling a comatose Rayne under a flyover and rushed her to a nearby pharmacy to revive her. He managed to resuscitate her, and Rob accompanied Rayne to Holby City Hospital's emergency department for further treatment. (CAS: "My First Day")
