In The Birthday, Stefan and Klaus are in Tennessee. Stefan stops a brunette/black haired woman from running out of her house, while being chased by Klaus. The girls give up Ray Sutton' s location, a werewolf, butKlaus tells Stefan to kill the blonde quickly and make the runner suffer, before walking out. Stefan obliges. Then Klaus and Stefan arrive at a bar to find Ray.
Ray is suspicious and soon figures out that he's in the company of vampires. Stefan's compelled everyone in the bar so Ray is all alone - and refusing to give up the location of his pack. Still, that doesn't bother Stefan, who menacingly suggests that they're going to play a drinking game - "truth or wolfsbane". Back in the bar, Ray's being tortured, he's chained up and Stefan's throwing wolfsbane soaked darts at him. He's still refusing to give up details of his pack. Fortunately for Ray, he gets a slight reprieve when Klaus gets word that Damon has been sniffing around.
Stefan promises to go and deal with it - and vows to return to Klaus. Damon meets Stefan who tells him to stop causing problems. Damon, of course, claims that he doesn't care about Klaus, but Stefan tells him again to let him go. Damon warns that if Stefan carries on, they'll be no saving him, but Stefan says he doesn't need that - though Damon points out that Elena thinks differently. Stefan, at this point, shows just how far he has fallen. He calls out to Andie, who is up high on a beam in the studio roof. Terrified, she sobs that Stefan has compelled her and she can't move. Damon tells Stefan that it's "not cool" but Stefan chillingly replies: "Oh, come on. A little bit cool".Stefan calls Elena.
He then tells Andie that she can move, she falls and breaks her neck. Stefan returns to Klaus, who has extracted the wolf pack information from Ray. Klaus announces that he now has to go through a three-stage process. First, he feeds Ray his blood, and then he swiftly breaks his neck. Klaus says he knew Stefan would come back, and Stefan, for his part, claims that he doesn't care about anything anymore. Interestingly, Klaus accuses him of putting on a "good show".Stefan in The Hybrid
He says Stefan will never stop caring about his family, but the blood makes it easier to let go. Later Stefan leaves the bar in Tennessee. He calls Elena, but when she picks up he remains silent, Elena realizes who is on the phone. She tells him he will be alright and tells him to hold on to the fact that she loves him. Stefan nods and begins to cry. In The End of the Affair, it is revealed that Stefan use to be a lover of Rebekah, an vampire and Klaus' sister.
Klaus takes him to Chicago about their memories (who was erased by Klaus) and their days and Rebekah is now dead, waiting for her resurrection.

She knows he has a plan, and warns him that Klaus is smart and will figure it out. As Gloria starts to search for Rebekah's necklace, Stefan begins to worry that Elena will be found. Gloria later says that what she saw in her vision bothered her, that the girls she saw were talking about him. She tells him he could tell her, or she could torture him for it. As Stefan speeds to attack her, she only glances at him and he falls to the floor in pain.
Gloria sets up everything to torture him for the information, and finally sees where the necklace is. Katherine arrives and stabs Gloria in the neck. Katherine offers that they should work together, yet Stefan still refuses. Stefan goes to where all Klaus' family members coffins are held, and almost opens one before Rebekah comes in. He asks her out about the man that was looking for them, but she give him a straight answer. She kisses him, testing if he has any feelings for her, and is disappointed, asking him if he would ever love someone like his previous girlfriend (Elena).
Klaus comes in a few seconds later telling them Gloria is gone, and Rebekah says Stefan isn't on their side, that he's been asking about Mikael. Klaus attacks him. He is shown to wake up in the back of a truck, where Klaus welcomes him back to Mystic Falls - to find out what Stefan is hiding.Stefan fights Klaus' compulsion.
Klaus started using mind compulsion on Stefan in The Reckoning, to get Stefan to obey to his orders and kill two students, Dana and Chad. He then compelled him to kill Elena if the clock reached 0. Stefan showed great strength when he fought the compulsion and told Elena to run. Unfortunately, Klaus then used compulsion one last time and ordered Stefan to turn his emotions off. Stefan was forced to attack Elena. In the end of the episode, Stefan is shown back at the Salvatore boarding house, saying as Klaus left town, he's been ordered to keep Elena safe (for the reason that her blood is needed to create hybrids).
His attitude is much like that as when Damon first arrived in Mystic Falls in the season one premiere. In Smells Like Teen Spirit, Stefan goes back to school and has moved back to Salvatore Boarding House again, staying behind to keep an eye on Elena, and "guard" her for Klaus. Damon is unimpressed by his brother's behavior, most importantly the way he is feeding off of girls in the house. As Rebekah enters telling them Klaus left her behind and she doesn't have a place to stay, Stefan shows he doesn't really care about that."Elena, do you have any idea how pathetic that makes you?"
Elena, Damon and Alaric later formulate a plan to catch Stefan off guard and lock him up, to try and restore him to his normal self.

After Lexi disappears, Stefan asks Elena if she's given up, but Elena says no, but Stefan couldn't either, because he would lose her if he did, she would not love a ghost.
In Ordinary People, Damon frees Stefan, seeing Lexi's approach as useless.Stefan's reaction after Damon frees him.
The two of them go to a bar and drink, both beer and blood. Stefan asks why Damon he freed him, but Damon brushes the question off. Eventually, Mikael shows up and drives his fist through Damon's heart in an attempt to get Stefan to tell him where Klaus is, after hearing that Stefan is connected to him. At first, it seems as if Klaus' compulsion made it so that he didn't care, but he eventually agrees to lure Klaus to Mystic Falls. However, he later tells Damon that he did it to get freedom from Klaus, not because of any feelings for his brother.
Stefan tells them not to let their humanity get in the wayIn Homecoming, Stefan participates in the plan to kill Klaus, luring him to Mystic Falls by saying that Mikael is dead (in fact he was dead as Elena daggered him so Stefan could inform Klaus of this and not have Klaus' compulsion stop him from lying.)

Katherine later shows up and informs him that Klaus' hybrids have orders to kill Damon if Klaus is killed.
She tells him that she is going back to go through with the plan, but that will mean Damon's death. She tells Stefan to care enough about Damon to save him. After Stefan interrupts the plan, which results in Mikael's death, Klaus undoes his compulsion, and Stefan and Katherine leave.
