The Vampire Diaries: I Know What You Did Last Summer

After spending the summer enjoying her passionate relationship with Damon, and making sure that Jeremy is adjusting after his return from the dead, Elena is thrilled to move into the dorm at nearby Whitmore College with her new roommate, Caroline. Still believing that Bonnie has been traveling all summer and will soon join them, Elena and Caroline are surprised when a student named Megan shows up and announces that she will be sharing their dorm room. Katherine makes an unexpected appearance at the Salvatore house and pleads with Damon to help her now that she is human and vulnerable to her enemies. Matt and Rebekah return to Mystic Falls after spending a wild summer in Europe, where they met a mysterious beauty named Nadia. Elena can't shake the feeling that something is wrong with Stefan, and Silas makes a terrifying appearance at the "End of Summer" party in the town square.

Episode Quotes
Damon: You okay?
Elena: Yeah, I just got this weird feeling like something bad is about to happen.
Damon: Well, it is. You're leaving tomorrow. You're trading all this for communal showers and a meal plan.
Elena: Can't you just be a normal boyfriend, and support me as I attempt to have a normal college experience?
Damon: I'd rather ply you with champagne and spend the night convincing you to stay.

Elena: We're in college, Caroline.
Caroline: We actually made it. We're here.
Bonnie: (they can't hear her) We're all here together.

Katherine: You're going to have to cut me off soon. My tolerance is a joke now. It's just so...glorious.
Damon: You're miserable.
Katherine: Please. I'm Katherine Pierce. I'm a survivor.
Damon: You're a liar. Your hair is messed up and your nails are chipped. You're a sad, miserable, human being and you want me to turn you.

Damon: One day. One day where you don't screw it up.
Jeremy: Leave me alone, Damon.
Damon: You're lucky you didn't put one of those idiots in ICU.

Damon: If I have to hear the word doppelgänger one more time, I think I'm going to actually have to learn how to spell it.

Episode Goofs

When Silas kills Bonnie's father on stage at the End of Summer party, he has used mind control to make everyone in the town square unable to speak or move a muscle. Bonnie begins to scream and fall to the ground. The camera angle switches back to the stage, and when it switches back to Bonnie again, there is a completely different woman standing behind her.
