Lance Robinson is a character who is introduced in Season Five of DEXTER as a serial killer of homosexual men. Lance is targeted by Dexter for a ritual kill in an attempt to "get back on track." However, Lance ends up dying as a way to save Dexter from being caught.
Lance is a fairly muscular man with mid-length brown hair that's fashioned to partially stick up. He wears a yellow T-shirt with pants.
His personality goes relatively unseen but apparently he is a homosexual man who murders his erotic playmates using their own fantasies against them. To find his victims, Lance places ads inviting homosexual men to participate in sexual activities, but his actual intent is to kill them. When Lance introduces himself to his targets, he initially acts friendly and flirtatious.
Lance is responsible for killing at least four men who had met with him for casual sexual encounters..
Dexter approaches Lance via an ad for some sort of sexual fantasy and they arrange to meet. Lance walks up to him thinking they're about to hook up, only for Dexter to inject him with M99 which knocks him out. Dexter quickly takes Lance inside a RV and proceeds to wrap him in plastic. As Dexter is about to start his kill ritual, Lumen Pierce interrupts with a phone call. She frantically asks for his help, saying that she had shot one of her rapists. Now having to deal with this new situation, Dexter hides an unconscious Lance in the back of his vehicle. Irritated at Lumen, Dexter rushes to her location -- a warehouse -- while hoping that the M99 doesn't wear off on Lance.
Inside the warehouse, Dexter finds a blood trail and he and Lumen track down Dan Mendell, the man that Lumen had shot. After confirming that Dan is a rapist, Dexter snaps his neck. Unfortunately, Lance now awakes, escapes Dexter's car, and makes a run for it, causing Dexter to immediately give chase. Meanwhile, Debra Morgan, Vince Masuka and two Paramedics are nearing their pathway. Just before Lance makes it into their flashlight beams, Dexter grabs him and strangles him on the way back to the warehouse. With quick thinking, Dexter formulates a plan. Unable to dispose of Lance in the normal fashion, Dexter leaves his body next to Dan's and makes it appear as though they had killed one another. During the crime scene investigation, Masuka's wild, sexual imagination creates a scenario that ultimately bails Dexter out of hot water. Both Lance and Dan's bodies are brought to the morgue and the case is (temporarily) closed.
