scene, claiming the low clearance rate as unacceptable. Debra continues to search after a visit from the call girl's father, leading to her discovery of Matthews' involvement. LaGuerta used the information on Tom and betrayed him and had him forcibly retired by the board when she told them. Tom believed it to be Debra who sold him out but she stated she never would do that. Debra confronted LaGuerta for using such a low tactic, knowing full well she did it for her own personal gain. As such, LaGuerta will now take over Tom's position, possibly as Deputy Chief. After much absence, Tom is finally brought back during LaGuerta's suspicion that Dexter is the Bay Harbor Butcher.

Dexter then tells him about a boat Doakes once had to lead him off the case which has Tom believe him. He tells LaGuerta about this and she doesn't believe him stating she would have known if Doakes had a boat. They find a tackle box from the old cabin with a key inside to
