So, yes, Hayley is encouraging Kim to break her sire bond, but Kim is finding it more annoying than encouraging. She thinks she's suffering now? She should have watched The Secret Circle. Hayley exposits about how turning 'til it no longer hurts will break the sire bond, but we already know that song.
Tyler shows up at tells Hayley about Caroline's pageant date with Klaus, which will buy them another day to help unsire the hybrids. While Kim screams in bone-breaking agony, Hayley suggests that they attend the pageant, together. Her excuse is that it will help them keep up their romance ruse, but we know she has designs on Tyler, because have you seen Michael Trevino? (Note to vision-impaired readers: he's sick hot.) Even as her bones continue to break, Kim screams at the two, in frustration. "GUYS, LIKE THIS ISN'T TORTURE ENOUGH! CAN YOU TAKE IT OUTSIDE?" Oh my word. I love her. Can we keep her, Show? You know how I just told you to do better. Here's your chance. M'kay? Ignoring Kim, Hayley tilts her head and bats her eyelashes at Tyler. He considers her for a moment then says, "Fine. We'll go." On his way out, he adds, "Wear a dress."
Gilbert Gables. Night. Elena is having trouble fastening her necklace. Jeremy stops outside her room and asks if she needs a hand. As he gets to work on the clasp, Elena tells him she picked up his dry cleaning. Jeremy looks at her reflection in the mirror and says, "I really wish you'd stop acting like you were still my sister." With that, he pulls the necklace tight around her throat. As Elena struggles, her neck starts to bleed. Jeremy wakes with a start. The Elena haters go into fits of apoplexy. As the now awake Jeremy struggles to catch his breath, he looks around and finds a knife and freshly carved stakes (which bear the same symbol we saw on Connor's stakes). His confused expression makes it clear that Jeremy doesn't remember carving them. Commercial.
The next day, as they're getting all prettied up for the pageant, Matt questions Jeremy about how he could have woken up with a knife in his hand and not know how it got there. While Matt is sure the Hunter's Mark is to blame, Jeremy worries that it the psycho-killer protect-o ring could also be to blame. What if, like Alaric, he's developing an alter-ego. I hope it's both, personally. Matt reads some hunter research which seems to support his theory that hunterdom is to blame here, though. Rising to his feet, Matt says, "You're not having a psychotic break, Jer. You either tell Elena, or I will." Well honey, it's sort of like a psychotic break, even if the forgetfulness is a passing thing all newbie hunters experience. Regardless of what we call it, or its cause though, surely he should tell Elena, anyhow. Jeremy agrees. He'll tell Elena when he sees her. Just then, Jeremy gets a text from Shady Stefan: "Meet in Lockwood Cellar. Don't tell anyone." When Matt asks Jeremy if he needs a ride to the pageant, Jeremy tells him to go ahead. He'll meet him there. Okay, that's dumb, Jeremy. Never go meet a Salvatore without telling at least one person. Also, its dumb, Show, that Matt came over to get prettied up with Jeremy, but then isn't disturbed when his bud (who isn't driving yet, as far as we know) doesn't need a ride.
