S6:E2 "I want to make sure I can rely on you." - Professor Gellar
The second episode of the season began with Dexter going through his bedtime ritual with Harrison and telling a story about how he slayed a bad monster named Chino, who was terrorizing a place called "the hood." Dexter concluded the story by saying he took Chino's body and put it in a place no one would ever find it, and Harrison asked if his dad put Chino in "daddy's box." Dexter was taken aback by how quickly his son was figuring him out, and found it troubling. Across town, Professor Gellar and Travis brought pieces of mannequins out of the trunk of a car and into some abandoned house. Travis told the Professor he would be a little late tomorrow, and this made the Professor worry about his commitment. It turns out Travis just went to visit his sister and as they sat down to dinner together, his sister convinced him to blow off "work" because they never get to hang out anymore. He agreed to stay the night and catch up with her, but he was acutely aware of how his choice would mean problems for him later.
"Freshly squeezed orange juice. Well aren't we the fucking Kennedys." - Debra
Since last season Debra moved into Quinn's house, indicating their relationship was sailing along smoothly towards marriage. One morning, Quinn got up early and made pancakes, which threw Debra for a loop. But she didn't really suspect anything until she opened the refrigerator and saw a black suede box sitting on a shelf. By the time she retrieved it and turned around to face Quinn, he had gotten down on one knee. Debra asked him what he was doing and Quinn said since they'd been dating for a year and were practically living together, he thought getting married was the next logical step for them. Deb stated she was still confused because they'd never talked about marriage, and said she needed some time to think things over. Eventually she came to the conclusion that while their relationship was great and simple, she wasn't entirely sure she wanted it to be permanent.
"What is that holy piece of shit doing here?" - Quinn
As Batista told the detectives to continue investigating the death of Omar, the fruit stand owner, Mos Def walked onto the set! Mos Def plays Brother Sam this season, and he owns a body shop that employs ex-cons and helps rehabilitate them. He had come to the station to answer some questions about Omar's death because he used to work at his body shop. The other cops told Dexter they were almost positive Brother Sam's operation of giving former convicts jobs was a sham, and so Dexter decided to investigate him and see if he fit Harry's code. Then Dexter remembered Brother Sam used to be a criminal - in fact, he was charged with a few hold ups and one time killed someone who fought back. Dexter had plans to kill him years ago, but Brother Sam was arrested for drug possession and hauled off to jail before he had the chance to strap him to a table. Sam re-emerged religious and with the goal of helping others -- but based on Dexter's own inability to change, he was convinced Brother Sam's "holier than thou" attitude was just a way to make it harder for the police to catch him misbehaving.
"Harry was one of the good ones, and so are you. And that's why I'm making you Homicide's new lieutenant." - Chief Matthews
After Debra stopped a shootout last week at a bar, she became an internet sensation and impressed Chief Matthews with her skills. He saw an opportunity to use the public's fascination with her to improve the station's reputation and so instead of making Batista the next lieutenant, Matthews pulled her into his office and offered her the job. She was shocked, but felt bad because she knew Batista believed would be the one with the promotion. Later, Deb raced over to Dexter's house to figure out if she should formally accept the position even if it meant hurting Batista. She confessed she always knew how to be a good cop because her father had told her how to be one, and the idea of doing a job without any of his advice was scary for her. The next day, Deb approached Batista and told him Matthews gave her the lieutenant job, and added she wouldn't accept the position unless it was all right with him. For a minute it looked like Batista was going to unload heaps of anger onto Debra, but then he hugged her and said it was great news that a real cop would finally be in charge.
"'Good Shepherd.' What does that mean exactly?" - Dexter"Well, uh, the men you see here, they're like my flock. And, uh, my job is to make sure they don't wander." - Brother Sam
As a way of getting closer to Brother Sam, Dexter rear-ended his car into a dumpster and took it to his auto body shop. After inspecting the damage, Brother Sam told Dexter that because he killed a man and was never charged for it, it was his duty to spend the rest of his life helping others. Dexter inquired if Brother Sam still had the urge to kill, and Sam replied in the affirmative - but said combats them every day by remembering how many people he hurt and using that guilt to propel him forward in a positive way. Sensing there was more to Sam than his day job, Dexter followed him late at night to a house where inside, he heard a gunshot. Then he saw Sam come out the door and put a body in the trunk of his car. Dexter assumed he had proof that Sam wasn't a changed man, and so he followed him back to the body shop to kill him. But When Sam caught Dexter outside the shop, he lied and said the reason he had come was because he left the clicker for his garage in his car, and so Sam invited him inside to retrieve it. But once Dexter went inside the shop, he saw the man Sam had put into his trunk - alive. Dexter figured out the guy Sam pulled out of that house was one of his workers who had missed his shift that day because he was doing drugs, and Sam brought him back to the shop so he could sober up. Dexter was pissed he couldn't kill Sam now, but he didn't have much time to think about it because Julio (a gang member) and some guys wandered into the shop and confronted Sam for taking his worker back. They pulled a gun, but Dexter diffused the situation by pulling his Miami Metro badge out and sent the thugs running except for Julio, who casually wished Dexter luck in finding a man named Hector, a barber who went missing six months ago.
"I like things the way they are." - Deb
Deb finally went back to Quinn's apartment and told him she didn't want to marry him because she liked things just the way they were. Obviously this upset Quinn and he left before Deb had the chance to tell him she was going to be his new boss. Before Deb's promotional ceremony the next day, Vince told Batista he figured out the snakes found inside Omar's body had come from an environment where the water was toxic, and this was their very first lead on the case. The next thing we knew, Dexter had strapped Julio to one of the chairs in Hector's old shop and slit his throat in one of the hair-washing basins. Not surprisingly, Dexter made it home just in time to give Harrison a bath, and came to the conclusion he would have to spend the rest of his life lying to his son to protect him.
