When Caroline arrives at the carnival, she smells the blood and ends up draining the man of all of his blood, killing him. Mason quickly breaks up the fight, but not before showing super human qualities leaving the worker battered. The carnival goes off without a hitch, until Damon compels a carnival worker to provoke Tyler Lockwood into fighting him because Damon believes he has supernatural abilities.

Tyler finds the moonstone, but does not tell his uncle about it. Tyler finds his uncle Mason searching for what he says is a family heirloom called a moonstone. Because she planned a carnival, she decides to check herself out of the hospital and go to the school, but not before feeding on a nurse. She steals a blood bag and drinks it, completing her transition. Since Caroline is a newly turned vampire, she wakes up in the hospital craving blood. Back at the hospital, Katherine shows up and knowing she has Damon’s blood in her system, kills Caroline to cause her to transition into a vampire leaving the message “Game On” for the Salvatores with Caroline. Because Jeremy is wearing Uncle John’s ring, he comes back to life as it protects him from death by a supernatural cause. When Damon is rejected by both Katherine and Elena, he snaps Jeremy’s neck. At the hospital, Caroline is in critical condition after the car crash, so Damon, Bonnie and Elena decide it is a good idea to give her Damon’s blood to ensure she heals quickly. Stefan quickly checks and realizes he did not take enough pills to kill himself so he is still human. She discovers he drank vampire blood and then took a lot of pills to try to die to become a vampire. She immediately thinks of Jeremy and checks on him. Upon returning home from the hospital, Elena finds Uncle John in the kitchen with his fingers cut off and stabbed in the abdomen.
