A totally transformed Caroline?!? A mysterious werewolf device?!? Major heat between Bonnie and Damon?!?

This week's installment of The Vampire Diaries has given our staff plenty to analyze and discuss. Join us as we do exactly that in the latest edition of the TV Fanatic Round Table...

What was your favorite quote from the episode?
M.L. House: The words from Stefan to Elena that must have melted the hearts of every female viewer: "I came back to this town to start a life with you. We can't forget to live it."

LJ Gibbs: My favorite quote wasn't as much a quote, but an expression. When Jeremy revealed that he'd put vervain in Damon's beverage, his classic eye roll indicated that he was not fearful in the least, but merely irked. Sigh. Can't a brooding vampire just enjoy a stiff drink after a long day? Ian Somerhalder is so great.

ViddWizard: Stefan's "Maybe they're ninja turtles." Gotta love that TMNT have become a mainstay of pop culture enough that this quote was funny to almost everyone.

Will new vampire Caroline survive the entire season?
M.L. House: Yes. We've been down the human-turns-vampire-and-then-is-killed-off route with Vicki. I can't imagine the show goes down the same path with Caroline.

LJ Gibbs: I'm cautiously optimistic, given the way she harnessed her new, murderous tendencies by the end of last night's episode, and I sure hope so! I loved Caroline anyway, and she's now been transformed into an entirely different, majorly bad ass character. Katherine may have competition for hottest vampire ever.

ViddWizard: She will... for my entire season. In other words, if they kill her off, I will be done watching the show, as all they are saying is that only Stefan and Damon are vampires worth keeping around.

What will happen first: Bonnie and Damon hooking up, or one trying to kill the other?
M.L. House: Katerina Graham told us that Bonnie will be "fun to watch" this season. I don't see a way to interpret that statement as anything but a tease for the inevitable Bonnie/Damon sex scene, do you?

LJ Gibbs: The writers love to shock and provoke, so I'll go with the hookup. Followed by another mystical attempt to burn him alive, possibly even in the same week.

ViddWizard: Were you not watching this week's episode? Bonnie nearly roasted Damon alive. I don't see how you get from that to cuddle buddies.

Were you disappointed by the absence of Katherine?
M.L. House: Wait... what? She wasn't in it?!? That was Elena?!? Man, Nina Dobrev is good. She had me fooled!

LJ Gibbs: No. She was absent physically, but certainly not in spirit, as her actions from "The Return" were on everyone's mind. Plus, you know what they say: Always leave them wanting more. Them being Vampire Diaries fans, of course. Pretty sure the Salvatores and Elena have had enough.

ViddWizard: Not really. I really like how much we got to see Caroline grow into her newfound strength. From her tossing Damon down the hall to controlling the lust around Matt, she is becoming a force to be respected.

What does the moonstone do and why is Mason after it?
M.L. House: It prevents a werewolf from being affected by a full moon. Mason is after it because this is a man who hates being placed in hairy situations... if you know what I mean!

LJ Gibbs: This show and its mysterious apparatuses. Perhaps the stone allows one to control or hide one's rage issues, much like the rings prevent the vamps from being exposed? Or it summons all local werewolves to cause mass hysteria on a moment's notice? I seriously have no idea, but love these constant twists provided by TVD.

ViddWizard: It a giant mood ring. It changes colors based on level of anger. It belonged Mason's mom. Or maybe it just keeps a cup of tea warmer longer... who knows.
