The next time he uses code, is before his brother had daggers him so he could go after her for her blood. His brother does not have to worry about either of their parents or anyone to distract him. Elijah had seen it coming. He had his suspicions, and texted her his location a minute before he felt it go through his chest.
It's ironic, his brother leaves to go find Elena. She was coming, after he left. She takes the dagger out of his chest and waits. He can hear, hearing is the first sense to come back. He hears her quiet worrying, and questions if he can hear her. He can, but his throat is too dry. He can't speak for a minute. When he can move, he tells her with a raspy voice, that she needs to leave. Immediately. He can't smell any other blood in the house. She shakes her head, as color rushes back into his skin.
"You need blood. I need you at full strength in case Klaus comes back. Drink from me." She says, aware she's dealing with a vampire. She has no delusions about what he is. He needs blood.
He shakes his head, she has a half minute before he can move his limbs enough to reach her.
When he stands up, she moves her hair to the side. She's stronger than he is for the moment, and she puts a hand on his neck and guides it to hers. She taps that it's okay, on his shoulder. He taps an apology as his teeth sink in. He uses the tiniest prick of his fangs that he can, he does not want to cause harm. He is not taking too much. He taps out blood, with his free hand that isn't supporting her neck. She doesn't tap against his shoulder for him to stop, doesn't signal. She trusts he knows when to stop. He pulls back, and bites into his wrist and offers it. Vampire blood is something she usually avoids, but it's Elijah and her head is a little light.
She asks what their plan is, as he moves away. He doesn't look at her for a moment, and then answers.
