Based on season Three of TVD...
Caroline throws Elena and Ellie a party at the Salvatore boarding house for their 18th. Klaus and Stefan learn Damon has been following them, so Stefan returns home and kills Damon's girlfriend, Andie, as a warning.
I...
Ellie's chest rose and fell, and she watched Stefan feed on Chad.
"It's always nice to see a vampire in his true element. The species has become such a broody lot." Klaus says.
Ellie stared at Stefan's back.
Stefan turned around and looked at Ellie, blood down his chin.

"No. You did this to him." Ellie said.
"I invited him to the party, love. He's the one dancing on the table." Klaus smiled.
Stefan used his hand to wipe his mouth.
The door opened again, and Rebekah walked in.
"Where is it? Where's my necklace?" Asked Rebekah.
"What are you talking about?" Klaus asked, looking at Rebekah.
"She has my necklace. Look." Rebekah says, handing Klaus the phone.
Klaus looked at the picture, then at Stefan.
"Well, well. More lies." Said Klaus.
"Where is it?" Rebekah asked.
"I don't have it anymore." Ellie says.
"You're lying!" Rebekah shouted, growling and biting into Ellie's neck.

Stefan moved forward, but Klaus pulled Rebekah off Ellie.
Ellie fell to the floor, and her hand went to her neck.
"Knock it off!" Klaus shouted.
"Make her tell me where it is, Nik." Rebekah said.
Klaus kneeled in front of Ellie.
"Where's the necklace, sweetheart? Be honest." Klaus said.
Ellie whimpered.
"I'm telling you the truth. Katherine stole it."

Stefan looked up at the ceiling.
"Katerina. Of course. Well, that's unfortunate. If we had the necklace... it'd make things easier for your witch to save your ex-boyfriend's life. Since we're doing this the hard way... let's put a clock on it, shall we?" Klaus said.
Stefan looked at the clock, seeing the timer set for twenty minutes.
"Twenty minutes. If Bonnie hasn't found a solution by then... I want you to feed again. Only this time... I want you to feed on Ellie. You know you want to."
Stefan stared at him. "No... don't. Don't. You know I'll kill her."
Klaus turned and walked away.
"Klaus. Don't do this to him." Ellie said.
"No one leaves. If she tries leaving, you fracture her spine." Klaus said, walking out of the gym with Rebekah.
Ellie gasped, staring at Stefan. He slowly turned his head to look at her.
Ellie looked at the timer ticking down.
Back with Matt, he was walking down a hall and on the phone to Bonnie...
Matt: "Did you find Jeremy?"
Bonnie: "No. I've called him, like, 20 times."
Matt: "All right. Let me grab my keys. We'll head to his house."
