She's aware that she's tied up, and when she's being put into the back of a car, and then she's confused. She hears doors opening, through her mental haze. There's bright light and she blinks blearily.
Someone picks her up, and someone else puts something to her lips. She accidentally drinks, she's expecting water. It's not, it tastes like vampire blood but she feels much better despite the horrible after taste it leaves. She asks to stand on her own, and she gets help to stand on her own for a moment before the person holding her lets go. She's not thinking too clearly, most people wouldn't just let a hostage stand freely, but everything hurts and she feels horrible.
There's a group of people, she discovers as she blinks a few times . They introduce themselves as werewolves. The leader tells her that she's the key to breaking the sun and the moon curse. Werewolves won't have to change if they get all of the necessary ingredients, including a little bit of her blood. It sounds like a good deal for them, vampires have freedom from the sun with daylight rings, helping out with this doesn't seem too terrible.
Elena can tell that they're keeping something from her. It sounds too good to be true, and in her experience, she knows it is. Her head is too light for her to think very clearly and so she just tries to agree with what they say. She needs to stay on their good side.
She does say that she needs to be back home, in Mystic Falls as soon as possible. They agree, and one person points out that they should leave. There are two cars, in the middle of nowhere, all she can see is grass, dirt and a blue sky. She has no idea where she is, there are no helpful monuments around for her to even have an idea. She puts her hands in her pockets and realizes her phone is missing.
Elena ends up in the backseat next to the girl who had picked her up. She hopes they can't tell she doesn't like this at all.
