Lacey is MIA for a spell, but Megan eventually tracks her down. Mother and daughter get into heated argument. Lacey's been frustrated by her mom's diligence in caring for her diabetes. Peter advised her to not let the diabetes control her. That's why she didn't answer her cell when her mom called. This leads to another heated argument between Megan and Peter.
Further investigations at the crime scene suggest that Wilson Polley actually did kill Niki. Megan believes someone let him out of jail, then let him back in after the killing. It's a wild theory, but right on the money. Wilson kills the prison guard he was in cahoots with to make a daring prison escape. He later calls Megan to congratulate her for foiling his little plan. The frightening thing is that the call comes from inside the building.
Everyone is at a baby shower for Bud and his wife. Megan is alone in the office when she sees Wilson heading towards her. The killer breaks into her office, knocks her out and ties her to a chair. When Megan awakens, Wilson taunts her with the embalming hook. He covers her mouth with duct tape. Wilson says he's going to make an exception with his latest prey. For Megan, he intends to rip out her brain while she's still alive.
DING! The elevator door opens. Peter steps out. He sees Megan tied up in her office, but Wilson gets the drop on him. A fierce struggle ensues as Megan works to free herself. Peter is in trouble. Wilson is beating on him close to the edge of the balcony. Then…BANG! Megan shoots Wilson in the shoulder. This gives Peter the opening to toss the serial killer over the ledge where he plunges to his death. Megan sees that her partner is hurt, and not just from the beating. The embalmer's hook is jutting out of his gut. He tells Megan that he's okay, but clearly he isn't. We're left with the unsettling image of Megan holding her wounded partner in her arms.
