"Oh, my god," Elle says, a heavy exhale, and she feels totally bad for this other girl, not to mention kind of embarrassed for the mistake. Like she's supposed to be able to tell them apart! All she knows is there's her and not-her. And also-not-her, apparently. "I am so sorry to break it to you like that. I thought, well, you're not me, so, like, you're probably Caroline, but you are clearly not. So that makes a grand total of three of us, I guess. Which I guess qualifies as a whole thing. It kind of depends on your definition of 'a thing,' but I think it totally counts. I'm Elle."

She almost offers her hand, but that's too weird.
