Sacha Levy is a fictional character from the BBC One medical drama, Holby City, played by Bob Barrett. He made his first appearance in the twelfth series episode "Talk to Me", broadcast on 5 January 2010. Sacha joined the Keller ward staff as a specialist registrar in general surgery. Sacha is the father of long-serving character Chrissie Williams's infant son, Daniel, as a result of a one-night stand, and has since held unreciprocated feelings for her. Since Chrissie's departure in 2013, Sacha's storylines have seen a relationship with Essie Harrison (Kaye Wragg) and a battle with depression. Barrett has reprised the role of Sacha in sister show Casualty in 2019 and 2023. Storylines Sacha has a one-night stand with Chrissie Williams (Tina Hobley). He then appears briefly in a locum registrar capacity, before, much to Chrissie's surprise, returning several months later on a six-month contract as a locum registrar on the hospital's general surgical ward, Keller, working alongside permanent registrar Jac Naylor (Rosie Marcel) and under consultant general surgeons Ric Griffin (Hugh Quarshie) and Michael Spence (Hari Dhillon). Sacha's post later became permanent, though he transferred to head up the hospital's Acute Assessment Unit (AAU) by director of surgery Henrik Hanssen (Guy Henry), after clinical lead Michael Spence became engaged working on the plastic surgery unit on Darwin ward with Sunil Bhatti. Sacha continues to work on AAU alongside Chrissie, and he tries to win her over several times. Despite this, she enters into a relationship with Dan Hamilton (Adam Astill), and they become engaged to be married. However, when Dan is revealed to be gay, Chrissie becomes closer to Sacha and realizes that he is the man for her as he is so nice. She then goes on holiday to Australia with him, and they later become engaged as well. When Sacha is stabbed by an unstable patient, Chrissie and Michael just manage to save him, despite a lot of blood loss, and it later causes conflict between Chrissie and student doctor Ella Henderson, who left Sacha to bleed out of fear. However, Sacha convinces Chrissie to lay easy on her. They marry, despite Chrissie's original concerns, and return to work on AAU. Sacha tries to help fellow doctor Luc Hemmingway (Joseph Millson), who is having problems and invites him for a turbulent Christmas dinner. Luc soon departs Holby after receiving advice from Sacha. Sacha befriends new doctor Gemma
