Spoilers for Season 1, Episode 12 'Born Free'.

You‘re the Moser middle child.

At age 4, after your mother’s brutal death, you and Brian were placed in a mental facility, where you kept each other company. Like Brian, you became a serial killer. Together, you’re known as the Ice-Truck-Killers.

Your big brother is talking to Dexter, trying to explain to him how you two are his real family. Not Debra. Not Harry.

"So while you were raised by the Morgan family we only had the memory of a family." Brian says

After a bout of silence, Dexter gets what Brian is saying. "Me."

"Imagine how we felt, when we tracked you down and found out you were exactly like us." Brian inquires, staring at Dexter

"I don’t have to imagine." Dexter assures

You two get out of your chairs and over to Dexter.

You grab the dagger, using it to cut through the tape binding Dexter to his chair and the two of you crouch down next to your little brother.

"We know what you’ve been going through all those years."

"The isolation, the otherness, a hunger that’s never satisfied." Brian continues.

"Well, you’re not alone anymore, Dexter." you grab his hand on the table, holding it gently with your hands, smiling at him "You can be yourself with us. Your real, genuine self."

After your little brother doesn’t answer for a few seconds, Brian goes on "Takes the breath away, doesn’t it."

Dexter puts his other free hand over yours, in a silent message that he accepts.

Brian and you both exhale in relief, and you slide the dagger under your hands.

"I think you’re ready for Debra." Brian murmurs.

-scene change, you three are in the shed of your childhood home, where Debra is taped down to a table-

"We’ve prepared her, just the way you like." you walk up to Dexter, who is walking around the room, seemingly shocked. Why? He should be happy he’ll soon be with his real family.

"This time, we’ll do it together." Brian announces, closing the door

"Does it have to be Deb…?" He can’t kill her. He only kills the bad people. Not his sister.
