I don't think there will be more. They already have enough mythology to play with. I'm very curious how the Katherine-Elena link will be resolved.

What the research assistant said about doppelgangers - how they are an evil alter ego, and exist to torment the person - got me thinking. Katherine isn't Elena's doppelganger, she's the original. It is Elena who's the alter-ego. That implies that Elena's purpose is to torment Katherine & destroy her life. Ooh, I wonder if there's a prophecy, maybe a link akin to Harry Potter-Voldermort.

Also, Tyler being a werewolf was in the books (although the TV show took a different tack on everything) and it was foreshadowed a long time ago, although in such a blatant way, it was hilarious.

Tyler acting like a jerk. Matt asks, "What's your problem, dude?!" Tyler, "I don't know..." and walks away. Shot of a full moon in the night sky. I turn to my sister and we both say at the same time, "He's a werewolf?" and collapse in laughter.

What I don't understand is how the gay community isn't all over this show. I have never seen so much prettiness together in one show. Usually we'd be glad to have one hottie. Here, my cup overfloweth. Stefan, Damon, Tyler (prettiest IMO), Jeremy (jailbait), Tyler's werewolf uncle (sexiest), Alaric (he looks average only compared to other guys), even the random extras are really hot, like the black guy who got eaten last week, or Anna's vampire who went on a date with Bonnie. Is is as good with the girls? I think Elena is ridiculously beautiful, and Bonnie & Caroline are very pretty, but they don't show nearly as much skin as the guys.
