He sets her in the room next to his, the one next to Elena's is Caroline's. Conveniently near Klaus's, but he doesn't say anything.
Her things are brought up to her room, and he notices something sticking out of her pocket. It's addressed to him. One of the letters she had mentioned. He begins to read, as Klaus carefully knocks on her open door.
He looks up, he's finished with the letter. He puts it in a pocket in his suit.
"Niklaus." He addresses.
"I have good news for you. Remember that vampire I almost killed? He has a witch friend who froze him into a coma. If you can get into his mind, you can get into Elena's." Klaus is grinning, and his brother wonders why.
"You're going to have to apologize to them." He points out.
"Already done. So many people can be easily bought these days. You have an hour before she reverses the spell. Here's the hospital address." The hybrid says, and Elijah wonders if he's doing this because of him, or a certain blonde vampire.
"Thank you, Niklaus." He says, and he's gone.
