Plot
Damon (Ian Somerhalder) wakes up tied up in a chair and with the fire poker sticking out of his chest thinking that Stefan (Paul Wesley) is the one who did this to him. When Stefan says that it was not him, Damon is sure that it was Mason (Taylor Kinney) who wants to avenge his death. Damon goes to Bonnie (Kat Graham) to inform her about it and asks her to fix it.
Elena (Nina Dobrev), after reading Stefan’s journals, believes that the only person who can tell her how to help Stefan get his humanity back is his friend Lexi (Arielle Kebbel). She asks for Jeremy’s (Steven R. McQueen) help to contact her but Jeremy does not know how to do it since he has never had an emotional connection with her and because of that he does not know how to call her ghost.
Bonnie hopes that the ghost who haunted Damon was Vicki (Kayla Ewell) but Matt (Zach Roerig) reassures her that Vicki is gone. Bonnie realizes that if Mason can physically interact with their world, then every ghost can do it. She goes with Caroline (Candice Accola) to the place where she brought Jeremy back to life to cast a spell asking for help. While she does it, her grandmother, Sheila (Jasmine Guy), appears. After the spell, ghosts not only can interact but also everyone is able to see them in town; Elena can see Anna (Malese Jow), Damon and Alaric (Matt Davis) can see Mason and Stefan can see Lexi.
