Woods: Caroline and Matt find a quiet place to kiss, but first they're interrupted by a distant growl. Caroline's too turned on to care, though, and gets rather assertive with her man. When she pushes him against a tree trunk, he cuts his wrist. She leans down to look at the wound, then kisses it and then licks it, because I told you Pudding Pops are DELICIOUS! Finally, she sinks her fangs into his wrist and freaks him out before attacking his neck. Fortunately for Matt, and for us, Stefan arrives and pulls her off. Matt falls to the ground and Caroline starts to regain her composure. They can hear the wolf circling, so Stefan says they'll have to run off to lead the wolf away from Matt. UM!? What if that plan fails? Nobody listens. They just run -- at least until they find Tyler who is just ascending from the Dungeon of Doom. Before the trio can talk, Caroline is jumped by the werewolf. It leans over her slobbering and growling until Tyler yells a authoritative, "NO!" No one is more shocked than he when the wolf runs off. I wonder if that moonstone he found last week makes him Uncle Brick House's master or something. I also wonder why Ty didn't turn when Mason did. Is it because he was underground and out of the moon's reach, or is it just not his time? [If they keep living together, maybe their cycles will sync up? - Zach]
Woods: Caroline compels Matt to think an animal attacked him and bit his neck. When she asks Stefan what to do about Tyler, Stefan says he "took care of it." Caroline mustn't know that Stefan's diet leaves his compulsion powers a little lacking, because she just accepts this, which is not her way. Anyhow, Stefan says they'll need to start Matt on vervain to make him less of a temptation to Care Bear. She's overwhelmed with guilt and regret. Matt is the last person she ever wanted to hurt. She wonders if she should leave him. Stefan says he can't help her, there. He knows he should have walked away from Elena, but he just can't.
Meanwhile, Tyler finds Mason's truck. He looks in the busted rear window and finds his supernatural mystery uncle's shorts. Lordamercy, you know what that means? Here Mason comes now, artistically smeared with mud -- which I'm sure was a terrible chore for the makeup artist on the show. Poor thing. Look at that, will ya? He's a brick HOUSE. He's mighty mighty, just letting it all hang out... but not for long. He asks Tyler for his shorts, and Tyler complies. Party pooper. There's probably other talk between them, perhaps even an acknowledgement that Mason is the wolf, but I can't concentrate.
