Maureen "Little Mo" Slater (also Mitchell and Morgan) is a fictional character from the BBC soap opera EastEnders, played by Kacey Ainsworth from 18 September 2000 to 26 May 2006. Little Mo originally appeared with a turbulent marriage with her abusive husband Trevor Morgan (Alex Ferns), but she fought back at Trevor – leading to her arrest in 2002; she is later released and Trevor's campaign against her ends with his death on 1 November 2002. Following Trevor's death, Little Mo proceeds to marry his sworn enemy Billy Mitchell (Perry Fenwick) – who had grown to care and bond with Little Mo during her ordeal. However, their marriage ends after she gets raped by her friend Graham Foster (Alex McSweeney) and discovers she is pregnant by him; the storyline that signals the end of Little Mo's marriage with Billy contributes to Ainsworth's maternity leave in 2004. The character soon reappeared with her baby son, Freddie (Alex and Tom Kilby), and later embarks on an affair with her brother-in-law Alfie Moon (Shane Ritchie) – which is later discovered by her sister and Alfie's wife Kat Slater (Jessie Wallace). Later on, Little Mo develops a relationship with habitual doctor Oliver Cousins (Tom Ellis) – though they soon break-up when she is accused of hurting Freddie. However, while her family and friends suspect Little Mo to have hurt her son, the real culprit is revealed to be Billy's little cousin Ben (Charlie Jones). After breaking up with Oliver and finding herself subjugated to accusations from her local community, Little Mo leaves Walford in May 2006; with the character being written out of the series in the process.
