In season 2 of Dexter , Debra meets and starts a relationship with Frank Lundy. This ends when Lundy goes to work his next case in Oregon. In season 4, Lundy is back in Miami having retired and is pursuing a case in his own time. My question is, why didn't Lundy tell Debra about his upcoming retirement plans to keep their relationship going? N.B. I am up to S4E1 Living the Dream , so please use spoiler tags where appropriate.
