As far as we're aware, the clip itself isn't online yet, but thanks to Mr. Video, we have screen captures from a scene that's in the February 14 episode of The Vampire Diaries, which is titled "Down The Rabbit Hole."
This clip might be of particular interest to "Stelena" (Stefan and Elena) fans as the two of them are interacting on the beach and possibly even smiling at one another. Rebekah (Claire Holt) does not look pleased.
Once the clip itself makes its way online, we'll update the post. But for now, enjoy the screencaps. Official images from "Down The Rabbit Hole" can be found here.
(If you like the caps, please link to KSiteTV rather than posting onto your own sites/Tumblr blogs/etc. Thanks!)
