It's definitely something to be concerned about, the fact that they can't be compelled -- but Rebekah's not really focused on that at the moment. This is far from the first time she's kissed another girl -- she's lived a long time, that doesn't come without some experimentation. But this feels different than curiosity or mild attraction. It's something stronger, almost electric. Perhaps it's because Quinn's the first girl she's allowed herself to truly get close to in a long, long time (always traveling with her brothers didn't leave a long time for a lot of girlfriends). It could be a lot of things. But she doesn't care about the reasons at the moment -- what she cares about it how good it feels and how even though she doesn't know exactly how this started?

She doesn't want it to end.

Which is why she steps in closer to Quinn now, letting one of her hands slip from her cheek up to her hair, tangling itself there.
