Tyler is seen sleeping in the hospital with a deputy guarding his door. Connor takes down the deputy, overpowers Tyler, injects him with a paralyzing agent, and proceeds to extract what Damon later describe as "Werewolf Venom".

Next morning Stefan is prepping a vintage motorcycle. He is determined to take Elena out to have some fun. Damon mocks him saying "those who can't do it, teach it". He declares that, following their agreement, he will leave town because Elena chose Stefan - after he kills the vampire hunter. Stefan declares that the bargain is void because Elena became a vampire, and now will have to go through the whole process of choosing one of them - again. He is totally fine with Damon hanging around to help with the transition. He is only mad because they shared blood.

Elena and Matt are meeting in their old make-out place for Elena to feed on him. She feels guilty that he has became her walking blood bank, but he says he wants to help. He knows he owes her his life. He questions her on her wisdom on going to school, but she says it would be more suspicious if she didn't. Besides, she does not want to bail on her Senior Year. They learn there is a curfew for kids all ages, because of the attack on Tyler. Matt says the town is freaked, and Elena quips "If only they knew the truth..."

When Tyler arrives home with Carol, Klaus is waiting for them. He can't make any more hybrids, and somebody is trying to kill one of them, so he brings three hybrids to body-guard Tyler. Although he is angry at Tyler and the group for stopping his heart, he decided to bring more hybrids to the range of the Hunter to protect him.

It's the first time Elena is back in Alaric's classroom and she is all sentimental and teary eyed.(the blackboard reads "Civil War", the topic they were discussing when Stefan first walks into the scene with all that first hand knowledge in the Pilot).

That changes in a heartbeat when Rebekah enters the room with invitation for a Curfew party in her new house. She invites Elena to "bury the hatchet ", but the look in Elena's face says that she would like to "bury the hatchet" in Rebekah's back. She probably already forgot that Rebekah helped Stefan kill the guard all the way back in Growing Pains. Elena provokes her by asking why she would leave the one person in the world (referring to Klaus) that actually likes her. Rebekah retorts that Stefan used to like her, but we can see she is hurt. Stefan joins the provocation asking her if she has nowhere else to go. She replies that history is her favorite subject, but ops, she killed the history teacher. Elena takes the bait and throws a pencil at Rebekah, but she is faster, catches the pencil and throws back, hurting Elena.

While Stefan is trying to teach her some anger management techniques, they see Connor approach Jeremy. Stefan tells Elena to go clean herself, and he will see what it's about. In the bathroom, Elena throws away a her cardigan with blood on it, and starts to clean herself. Heather walks in with a bloody neck. She has been sent by Rebekah, who walks in after her, and provokes Elena with Heather's blood. Rebekah now knows there is Vampire Hunter in town.

In a Math room, Connor explains to Jeremy that only vampire hunters, or potential hunters can see the ink. It's their "hunter's mark". Stefan is overhearing, and signals Jeremy that he is around. Connor proposes a deal. If Jeremy brings him a vampire, Connor will train him to do what he does. He suggests Jeremy should start with his "friend with a bandage on his neck". Out in the woods, Damon finds Connor's trailer. He does not need an invitation, but the place is booby-trapped. He gets two harpoons connected by strings to a device - could be a bomb. Damon looks surprised and annoyed.

Back at school, Elena is feeling murderous. Caroline congratulates her on a valiant first day effort, Stefan invites her to skip class and go with him have some fun. It seems that students will still graduate even if they don't actually watch classes. Elena's idea of fun is to go to Rebekah's party to show she is not intimidated. Great plan.

Stefan seems to know exactly what Elena needs to do to deal with all that murderous anger. Too bad he cannot do it himself. Caroline tells him he is good at this, and should write a self-help book for vampires. Tyler is under house arrest. A pretty werewolf named Hayley shows up. She helped Tyler break the sire bond by chaining him down. She is impressed by the fact he is loaded and mock hurt that he left the pack, left no forwarding address, never called. He claims it's because he wanted to protect the pack - Klaus was still turning all werewolves into hybrids (he wanted to keep the cursed with awesome just to himself.) She demands a fancy rich guy's Scotch and plops herself on a couch.

Inside Connor's trailer, Damon is still anchored to the bombs. Meredith shows up to help him, and asks why he did not call his brother. Damon says he is proud, and stubborn and that she is already there. He finds Pastor Young's letter about war, sacrifice and a greater evil coming to Mystic Falls. Meredith tells Damon that he is a good brother, because he is there strung up to a bomb while Stefan plays Vampire with the girl who broke his heart, and he is doing a good job of acting like it does not suck. Although she did not remove the barbs from the arrow, nor cut it in any way, Damon now can safely remove it.

Back at school, Rebekah invites Matt to the party, and kind of tries to justify/apologize in a very awkward way. Matt just ignores her and walks away. Connor confronts Matt about his wounds, and threatens to cut his throat if he does not reveal who is feeding on him. Matt lies and says Rebekah is the only vampire he knows in town. Elena is rummaging through Damon's drawers looking for "bourbon" but he guesses that she is looking for the White Oak Stake, calls her on it, while calmly undressing in front of her. As she gets visibly agitated, he reveals that he has been talking with Jeremy. As he unbuttons his pants, she leaves in a huff.

Connor is sitting outside his trailer, showing his dexterity by carving delicate symbols in wooden stakes with a very big knife, totally oblivious that his traps were sprung and the bloody marks on the table. Jeremy arrives, tells that there is a doctor in the hospital that uses vampire blood in surgery, so she must have a deal with one. Connor gets very angry. He says that when a town takes one vampire, word gets around, they feed, they turn, and soon you have a full infestation. It's so bad one of them is throwing a party - but he has that covered. All vampires who drink at the party will be dead by night. They can go straight to the hospital.

Caroline wants to spend time with Tyler, but is turned down because the house is full of hybrids. Klaus introduces himself to Hayley. He figures that Tyler might have had a brief affair with Hayley and gets angry at Tyler for cheating on Caroline.

Elena tries to connect with April, who does not believe the accident that killed her father was an accident. Rebekah interferes, steals Elena's ring and throws it in the garbage disposal unit. Elena manages to get it back before she burns badly. Stefan calms Elena down and stops her killing Rebekah and they leave; but not before Elena drinks from werewolf venom-spiked beer. Rebekah is visibly annoyed Elena is nonchalant.

Jeremy and Meredith lead Connor to his trap. Before killing him, Damon asks about this "greater Evil". Klaus is specially ticked, because he feels he is as evil as it gets. Connor says that if he is killed another slayer will take his place. He decides to detonate the bombs, killing himself and the two vampires at the same time! But not before Damon clues Klaus about the disappearing tattoos. Klaus says that Connor is "one of the five", but Connor seems to have no clue what it mean.

Stefan and Elena's passionate moment is stopped when the venom starts to affect Elena. She begins to hallucinate and see "Damon", who tells her she may be more like him as a vampire. Stefan quickly calls Klaus. While he is generally indifferent to her dying, he gives her blood. Rebekah has also been poisoned and is not feeling so well. Matt shows up and tells her in details why her life is horrible: she puts it on herself. She rips his heart out in a daze, but it is only a hallucination . Rebekah and April bond when April stays behind to help clean up.

Carol Lockwood is glad the sniper is dead, although she does not approve of Damon's methods. Meredith is mad at Damon for exploding the hospital and will not go out for celebratory drinks. She asks Damon to make up with his brother and Elena. Stefan calls on Caroline for help with Elena, which she agrees to. Elena, meanwhile, begins feeding on Matt longer than usual due to the events of the day leaving her angry and thirsty for blood. When she starts to get aggressive, Damon comes in and compels Matt to forget what Elena was doing. He decides to to teach Elena the right way of being a vampire...his way.
