Storylines Harry begins working at Holby City Hospital in June 2002. He is pleased when his old flame Selena Donovan (Liz Carling) arrives to carry out a drugs trial in the department, and invites her to dinner. He cancels a driving lesson with his teenage daughter Tally (Ashlie Walker), who asks her mother Beth (Lynda Rooke) to take her instead. They crash, and Beth is fatally injured. Harry blames Tally for the accident and develops an anti-depressant dependency, forging senior house officer Lara Stone's (Christine Stephen-Daly) signature to prescribe himself drugs. Harry clashes with registrar Simon Kaminski (Christopher Colquhoun) over his temperament, suspending him from work. In revenge, Simon begins sleeping with Tally (Holly Davidson). He learns that Harry has been self-prescribing and attempts to blackmail him. Lara notices the strained atmosphere between them, and Harry confides in her that he needs help, accepting her support. He misinterprets Lara's kindness, however, and tells her he is in love with her. His feelings go un-reciprocated, and Harry is angry when Lara sleeps with paramedic Luke Warren. On an outdoor pursuit day for management training, Harry leaves the marked route and becomes trapped in a cave. Simon rescues him, incurring a spinal injury in the process. Several weeks later, Harry discovers that Lara has begun a relationship with Simon. Tally takes the news badly and behaves erratically, leaving Harry no choice but to suspend her on the anniversary of Beth's death. When Simon mocks her, Tally attempts suicide by taking an overdose. She recovers, but Harry realises he has been neglecting her and takes her on holiday. Lara and Simon become engaged, but Harry discovers he has been cheating on her, taking Lara away from the venue on her wedding day. Simon dies in a plane crash en route to the wedding, and
