Little Mo first arrived on Albert Square on 18 September 2000, along with her family: father Charlie (Derek Martin), grandmother Big Mo (Laila Morse) and sisters Lynne (Elaine Lordan), Kat (Jessie Wallace) and Zoe (Michelle Ryan), although Zoe is later revealed to be Kat’s secret daughter following a family argument. They are also accompanied by Lynne’s boyfriend Garry Hobbs (Ricky Groves) and later joined by Little Mo's estranged husband Trevor Morgan (Alex Ferns), a handyman who surprises Little Mo with his arrival just days before they celebrate Christmas that year. It soon becomes clear that their marriage was previously troubled, due to Trevor being physically and mentally abusive towards her as a result of his servere mood swings and violent temper. This is further evident when Little Mo tries to leave her husband, but he deceives her into staying with him and proceeds to isolates his wife from her family – who despise Trevor due to his abusive nature. She always forgives him and even agrees to start a family. However, when he rapes her after she buys a hat to wear to Lynne’s wedding which he has forbidden her from attending, she realizes she cannot bring a child into such an environment and goes back on the contraceptive pill. She finally leaves Trevor when she discovers he had deleted a message from Zoe, who has run away from home. Eventually, Little Mo attacks Trevor, hitting him with an iron when he attacks her. She goes home thinking he is dead, but when she and her sisters return to the scene, he is gone. Little Mo is prosecuted and found guilty of attempted murder but is released after Trevor does a deal with the Slaters: he will not give evidence against Mo, if Kat does not press charges against him for assaulting her.
