Hendrik," now before we start everyone sign here". Caroline looks at it," what's it for"? Becky," it's a NDA"? Hendrik," yes". Damon," for what"? Hendrik," so you guys don't tell them where I'm at duh". Damon," Sneaky". Balthazar smiles. Everyone signs. Balthazar whispers to Hendrik,' what is it really"? Hendrik looks at all of them," it's a magic binding contract that if you hurt or try to get someone to hurt my family or I it one if your a witch destroys your family's magic. If your a werewolf binds your wolf. If your a vampire takes your vampiric abilities. And if your human kills you. Even if you have magic help". Damon," well I'll be Damned. Can you make one for your siblings"? Hendrik," yes. If they kill or attack or do harm to anyone by themselves or have someone do it for them they lose everything including Klaus's hybrid side. I'm not stupid a werewolf got me once. I won't let it happen again". Stefan,' now you sound like the devil". Balthazar," he helped you didn't he". Hendrik," uncle Lucifer helped me right the contract and making in binding". Damon," oh hell. Kid. You call Lucifer as in the devil. Satan himself uncle"? Hendrik," yes". Stefan," we are dead".
