Jim's attempts to manipulate Maxi backfire when he realizes she won't be intimidated and, even more shockingly, that she was responsible for Virginia's death. Meanwhile, Shaz and Barbara manage to intervene just in time to stop Di from making a huge mistake by calling off the wedding. Sylvia, who struggles with technology, takes credit for Barbara's project, leading Neil to assign her even more tasks. On the night of the canceled wedding, Barry confronts Di at her home, forcing her to question his true character. Desperate to regain control, Jim enlists Yvonne's help to deal with Maxi, who is blackmailing him regarding Virginia's death.
