[ remember that time this sexy musketeer told sam she was a vampire that couldn't stop thinking about blood? yeah well elena's not forgotten either.
that's why when she catches sight of sam it's a deer-in-headlights moment. she sucks in a breath, her eyes a bit wide as she gazes at him sidelong just long enough to perhaps be a little obvious about it. she's not sure what to expect and hasn't known what to expect. not after that day and how... loose everyone seemed with their words. (nice play, wardens.)
she tucks hair behind her ear and manages a smile. she guesses they should talk. she wants to talk.
she can only hope sam doesn't turn away in horror, disgust, anger (pick an emotion; elena wouldn't blame any of them) when she makes a move to approach him -- and said hope is apparent in her eyes. ]
