TEXT: [Mystic Falls' Square] (Elena rejoins Matt) Elena: Guess who! Matt: Hmm. I wonder. Elena Gilbert? Elena: Yep Matt: You're in a good mood Elena: Well, it's a good day. We're alive Matt: Yes, we are, and we are partying tonight Elena: Yes, we are Matt: So what did you want to talk to me about? Elena: Are you still drinking Vervain? Matt: No. I wear this bracelet in case anyone needs my blood, remember? Elena: This is gonna hurt me more than it hurts you Matt: What are you doing? I need that Elena: Long story short-- I'm Katherine, not Elena Matt: Katherine's dead Elena/Katherine: Not exactly. While you guys were all playing drinking games, toasting to what a horrible person I am, I was plotting a way to passenger myself into Elena's cute, little head Matt: Oh, my God Elena/Katherine: Anyway, I need a crash course on all things Elena Gilbert. She's in college now, all grown up, and I figured who knows her better than her compellable best friend? So what do you think? How's my dress? It screams safe and predictable. Am I right, or am I right? Matt: I'm not doing this (Nadia rejoins them) Nadia: Just compel him already Elena/Katherine: Take the fun right out of it, why don't you? Play along with my secret, Matty pants. Would Elena wear this outfit to a party? Matt: No to the dress, yes to the shoes Elena/Katherine: Now let's talk honestly about the red thing that's happening in my hair Matt: So you're dead and, what, hitching a ride in her brain? Elena/Katherine: For now until I make it permanent Matt: Permanent? How? Elena/Katherine: Hello! The hair. Why did she dye it? Matt: I don't know. She did it in New York right after she shut her humanity off Elena/Katherine: But her humanity's back now. Perfect. It's gone. Ok. What
SUMMARY:
In order to give Katherine permanent control over Elena's body, Nadia's friend Mia plans to cast a spell for which she needs to use Katherine's corpse. However Damon has already buried it himself, in the tomb where Katherine was supposed to have been buried alive in the 1800s. Katherine compels Matt to give her personal information about Elena so that she can impersonate her at Tyler's welcome home party, and hopefully learn the whereabouts of her corpse. Caroline reveals to Katherine (posing as Elena) that she slept with Klaus, which Tyler overhears and becomes extremely angry and hurt. Enzo brings Aaron Whitmore to Damon, who tells him to complete his killing streak and kill him (just like his parents and grandparents), however Damon declines. Katherine and Nadia are able to find Katherine's corpse, and then complete the spell. Later, Katherine (possessing Elena) breaks up with Damon, which angers Damon and causes him to attack Aaron in the final scene.
