belinda returns in january 2016 after charlie dies of a heart attack, and accuses kat of killing him as she was arguing with him when he died. an explosive argument then ensues between belinda and kat over charlie and mo, which leads to kat revealing that she had another son when she gave birth to zoe, and that mo knew about him. belinda believes that kat is just making excuses and leaves with mo. belinda returns later in january for charlie's funeral, and eventually manages to make amends with kat. however, when she makes a thoughtless comment about stacey, who is suffering from postpartum psychosis, kat throws a drink over belinda and then storms off. belinda catches up with her, and recalls the time when she, viv, little mo and zoe visited ireland and saw viv visit a couple with a boy; kat realises that was in fact her son. when stacey is discharged from the mother and baby unit, she arranges a family lunch and invites belinda, jean and jean's new husband ollie walters (tony o'callaghan). belinda learns that her cousin kyle slater (riley carter millington) is transgender and when jean is convinced kyle is lying, belinda encourages stacey to stand up to her. belinda then tells stacey and martin they will have to move out as kat and alfie promised to pay their rent for a year, which has now ended.
