If you are talking about the guy with the huge scar on his head, that answer is no. He wasn't being controlled by Daniel (Vogel's son) nor mailing brains to Vogel. He was a separate entity that was used to throw the audience off. Her son did use that one guy on the video tape but he killed him one episode later I believe.

when Joker killed that bytch, she's the only bad thing about that movie to me... she kept that movie from being Flawless!Got ya, I thought they had showed the guy on the tape holding the gun was dude w/the scar on his forehead. Damn this season has been horrible. Everybody this bish treats is a serial killer.
That fool wouldn't even listen to Blake on the bridge ... You think he makes wise choices
Quinn has always been a simp and a idiot, y';all forget nadia from last season?
yall forget how he was dating trinitys daughter and relaying information to her about confidential police leads?

Honestly they should have made her Masuka's love interest cause this father/daughter storyline ain't doin' it for me. Plus when Masuka told her to stop smoking weed and she was like "You can't tell me what to do outside work, I smoke what I want" was I the only one that was screaming at the screen "bytch YOU WORK WITH COPS! DON'T SMOKE!watching the episode now and god damn nicki (becky from FBL) ass stay clapping whenever she walks away on screen...
" Then again dem Miami Metro cops don't be solving crimes so whatever honey

Lol this show is beyond stupid now, Vince daughter goes to a crime scene where a murder happens late and high, then pouts when he sends her home. Angel doesn't say question it but why should he? He didn't run a background check or have-her take a drug test in the first place for a job in homicide. Vince sends her home that's cool she can come on coke or walk up with no gloves on to mess up the crime scene , angel will say bro its ok she will learn later. Angel is the worse cop in the world , how could he ever been made a boss?

Stopped watching this after the opening of season 7 but I always felt like the people who knew what they were doing wanted to end the show in Season 5 following Dexter's downfall due to Rita dying at the hands of Trinity, but instead the network opted to milk the show for as long as possible and replaced all the people who knew what they were doing with incompetent hacks.

So are there really devices that can take your baby pictures, age you and then match your baby picture in a database (with literally thousands of other faces) with an adult picture of yourself? 
me and my homeboy were just watching this just laughing at how awful that shyt was. nikkas might as well give Dexter superpowers and have him teleport to Argentina now.
Oh and Harrison falling of the treadmill and cutting his face was just I saw Hannah being recognized by the nurses coming from a mile away. MY GOD. And all the motherfukkers did was put a god damn band aid on his chin. 
At this point I just watch Dexter for the lulz and to get my mind stimulated for Breaking Bad.

You know this show went to hell when nobody mentions this is the final 2 episodes left. Even the network doesn't promote it anymore giving Homeland and Shameless more promo time. I bet Dex finds the killer while drinking coffee with Debra and captures him only to get caught up by Quinn and Matsukas daughter having sex next door to kill room Dex set up.
