Okay, technically, Elena was trying to deprogram Jeremy, it's just that she was sitting in the cabin so Shane could use the hypnotism-esque method of "persuasion" to detour Jeremy's desires to kill Elena. The plan was for Jeremy's subconscious to recognize her as someone he loves, someone he wants to protect. Then he can choose to take the detour as opposed to the conditioned response of kill. Elena had to speak to Jeremy when he was in this staid state and try to remind him that she's still herself. She told him how when their parents died, Jenna brought them to that lake house and it was like her parents were there with them. She said they'd want them to stick together now and fight for each other no matter what. Shane asked Jeremy how he felt about Elena now, and it didn't matter that the concept of "persuasion" was kinda hard to follow, because Jeremy's response was worth it: "She ruined our lives. She’s not even my real sister. She’s just the reason that everyone I’ve ever loved has died. She means nothing to me. I will kill her, even if that means I die myself." Shane snapped Jeremy out of it. "Did it work?" he asked. Not so much, Jer.
Caroline and Stefan were experiencing equally bad luck. Tyler overheard them talking about the need to keep Klaus around because he's the only way they have to find the cure since he has the sword, and he pissed that Caroline had shared his plan with Stefan. Stefan told Tyler to hold off on his plan, and Tyler told him he wouldn't. They'd already served up one hybrid for Jeremy to kill, and if they find the cure, all that means is that the hybrids go back to being werewolves who have to turn on every full moon. I wonder how far Stefan would've gone to stop Tyler if the hybrids hadn't shown up to take Stefan and Caroline hostage in the Lockwood family cellar. At this point, I still thought Jeremy or Tyler could be the character we'd have to say goodbye to. Both of them are a threat to what the Salvatores think is best for Elena, which makes them expendable.
At the lake house, Elena told Damon how strange it was that the last time she'd been there, she was so in love with Stefan, and now that's barely a memory. Was that the sire bond's work, or her being so happy with Damon that she's forgetting about Stefan? That wasn't attractive, right? Even if you want her with Damon, it's hard to like someone who can't remember someone she was SO in love with. That conversation gave Damon an idea: Professor Shane should have used someone other than the person Jeremy wants to kill to attach Jeremy's "detour feelings" to. "You. I feel that way about you," Jeremy said to Bonnie. The sweet, awkward smiles Jeremy and Bonnie shared made me say "Ahhh," but truth, I don't understand why Jeremy isn't trying to kill Damon on the spot like he did Elena. Is it just that he's got more pent-up anger against Elena, or did Connor's desire to kill Elena transfer with the mark?
Outside, Shane and Elena talked about her relationship with Damon. He said he'd once loved someone too much, too -- his wife and son had died and he'd been trying to figure out a way not to miss them. Damon interrupted them to threaten Shane's life (again), but Shane saved himself by saying he could lead them to the cure because he's already been there.
Before we dove into that confusion, we had to watch Tyler break the news to his mother who insisted he have a toast with her before people
like me could judge them. She accepted him wanting to switch bodies with Klaus pretty darn well all considering. How she managed to keep a straight face when Tyler said, "I’m their alpha, they’re looking at me to help them," I do not know. But she told Tyler his father would be proud of him -- he's a leader of people now just like his dad had been.
