After realizing that he was manipulated by Miguel, Dexter cannot gain the upper hand as Miguel threatens to launch an ethics investigation into Debra's relationship with Anton, a key witness in her case. Having rescued Anton after his encounter with The Skinner, she wonders if their relationship is worth jeopardizing her career for. Dexter takes Ellen's ring, a memento of the kill, from Miguel's house to use as evidence against him. Dexter also takes Miguel's shirt stained supposedly by Freebo's blood to a laundry shop.
