Cassie is lost and confused and Diana finally leads her to a creepy old abandoned house where the cast bombards her with the news that she's a witch. But not only that, she is the last piece to completing their "secret circle." Cassie of course freaks out and runs off into the woods which sets up for one of the most beautiful scenes I have ever seen. Adam catches up to her and decides to prove it to Cassie (why didn't they just do that to begin with?) They make magic together and all the droplets of water begin to float. 
Caroline and Tyler have spent their summer living as pseudo best friends but the tension is rising and something is going to have to change quick.

Klaus makes Ray drink his blood and begins what seems to be a hybrid army he is building. Stefan breaks down in the parking lot and calls Elena on a blocked number.

Never let that go.” Caroline ends up being shot with vervain darts by Mrs. Lockwood while doing the walk of shame out of Tyler's bedroom.
