Senior Prank Night...

...turns into a night from hell. When Elena, Tyler, Bonnie, Matt, Caroline, and a bunch of other students from Mystics Falls High get together for a senior prank night, their intentions are to make memories that will last the rest of their lives. Well they get memories all right, but probably not the ones they were hoping for.

Klaus leaves Stefan in the hands of Rebecca and heads to the high school where he finds Elena. Entering the gym, he pretends to be a teacher and bust the seniors, telling them to go home, except for two, Dana and Chad. He compels Dana to hold up her foot and Chad to beat her to death if she drops it. The goal, to make Elena suffer. Elsewhere, Rebecca reveals to Stefan that Klaus knows about Elena and he tackles Rebecca, demanding to know where she is. "You really do love her don't you? Consider me jealous." She stabs him with a crow bar and disappears to the school.

In Damon and Katherine news, Katherine has kidnapped Jeremy in the hopes that he can communicate with Anna. After showing Damon that she stashed him in the truck of their car, she tells him the Pearl told her about a way to kill Klaus, but never told her what it was. The only other person she told, was Anna.

Rebecca walks in on Caroline and Tyler making out. "You two are adorable," she says. "Ah, do we know you?" Asks Caroline. "You're Caroline, Elena's friends, which makes you Tyler, the werewolf." "And who are you?" Demands Caroline. "I'm the new girl." Rebecca attacks her and takes Tyler to the gym where Bonnie and Matt had just arrived to find Klaus and Elena. Klaus is fed up and grabs a hold of Tyler. As the rest watch in horror (minus Rebecca), Klaus feeds Tyler his blood, the same blood that killed the rest of his hybrid creations. "I need you to find a way to save my hybrids, Bonnie. And for Tyler's sake, you'd better hurry." He snaps Tyler's neck.

While Tyler and Caroline wait in the hallway with Rebecca, Stefan walks into the gym. "Come to save your damsel, mate?" Asks Klaus. "I came to ask for your forgiveness and pledge my loyalty." "Why, you broke that pledge once already." "Elena means nothing to me anymore. Whatever you ask of me, I will do." "Fair enough," replies Klaus, "Let's drink on it." He tells Stefan to killed Dana and Chad. When Elena steps up to counteract Klaus' demands, he slaps her and Stefan attacks. Done with Stefan's lies, Klaus compels him for his obedience and allegiance and Stefan kills the two kids.

After Damon slamming his head to threaten Anna for answers, she tells to Jeremy, who relays it Damon and Katherine, that Klaus and Rebecca are looking for a man named Michael, a vampire who hunts other vampires. She warns not to wake him up. .

While waiting in the hallway with Tyler and Caroline, Rebecca sees a picture on Elena's phone of her wearing the necklace. She bursts into the gym to tell Klaus and attacks Elena to tell her where it is. "Katherine stole it," she says. Unfortunately, Klaus wants that necklace. "Since we're doing things that hard way, let's put a clock on it, shall we?" He gives them twenty minutes. "If Bonnie hasn't found a solution by then, I want you [Stefan] to feed again. And this time, I want you to feed on Elena."

Knowing they need help, and sensing her presence all night, Matt concocts a plan to communicate with Vicki. He decides to drown himself in the pool and have Bonnie bring him back with CPR. If it is successful, he will have died and come back to life, the criteria that allowed Jeremy to see Anna and Vicki. After much tension and anxiety that Bonnie wouldn't be able to bring him back, Matt returns with a message from Vicki. He tells Bonnie that the reason the hybrids are dying is because Elena is still alive.

The clock ticks down to zero and Stefan holds on long enough to let Elena flee. The whole time I'm thinking NOOOOOOOOOOOOOOOO! Stefan, fight it! He does for a time, but Klaus has had it once again. He compels Stefan to shut off his emotions. There was a glimmer of hope when Stefan responds, "NO" at first, but that glimmer was quickly diminished as we see Stefan's eyes roll back in his head and his stare become blank. Klaus orders him to feed on Elena.

Now you're probably wondering, (hopefully unless you're emotionally deficient) what is happening to Tyler. On a hunch, Klaus feeds Elena's blood to Tyler, hoping it will cure another failed transformation...and cure it, it does. After a fit of convulsion, Tyler whips his head up to reveals his yellow wolf eyes and a brand new pair of fangs.

Elena wakes up in the hospital, where a compelled nurse is taking her blood for Elena's "friend Klaus" and administering a sedative. Damon, once again comes to the rescue. He threatens Klaus with Michael knowing his and Rebecca's whereabouts and carries Elena back to the boardinghouse. "He's really gone this time," she comments in anguish over Stefan. "I saw it happen." "Where were you, Damon?" She asks with eyes full of tears. "I shouldn't have left. I promise you, I will never leave you again." Stefan enters. Apparently, with Klaus in a temporary hiatus, he has left Stefan in charge of Elena. Yeah, that's going to work out splendidly.

With the night over, Tyler okay, Matt seeing Vicki, and Elena and Damon together (cough, still in speculation), we find Jeremy and Katherine in Shiloh at the tomb of the Michael, the only one who knows how to kill Klaus. Sliding the lid off his grave, the Micheal's eyes open...cut to the end title sequence.

As always, questions, comments, theories, ideas???
