Well, the show did it again.

The Vampire Diaries produced more shocks, twists and turns on "Plan B" this week, giving our staff plenty to dissect in the latest edition of the TV Fanatic Round Table. We encourage reader debate on the following topics in the Comments section below and/or in our Vampire Diaries forum. Let's get to it!

What was your favorite quote/scene from the episode?
M.L. House: Had to be the Elena/Stefan break-up scene. We always give props to Ian Somerhalder, but let's stop for a moment and recognize the work of Paul Wesley's. You could feel the pain in his eyes through the TV screen.

LJ Gibbs: Damon's "Katherine will only rip your heart out. Let me do it for her." I know he's killed a lot in his 150-plus years, but in terms of kiss-off segues before delivering the coup de grace, no way that's ever been topped.

The Barnacle: Damon's reaction to Katherine bedding Mason: "Werewolf thing aside, the guy's a surfer." Hilarious.

Did Caroline make the right move by compelling her mother?
M.L. House: For the sake of fellow Mystic Falls residents because the compulsion likely saved innocent lives that would have been lost in a battle between the police force and the vampires? Yes. For the sake of more much-needed mother/daughter moments? No.

LJ Gibbs: Definitely. Liz didn't like Caroline while she was alive, and now expects us to believe she wants a relationship with her undead daughter? Mom's heart-to-heart was clearly a ploy to walk out of the dungeon uncompelled and return with reinforcements. Caroline saw through it, then saw to it that her brain was wiped.

The Barnacle: No. Caroline may seem strong and self-assured now. But she's still an insecure mess inside. Without Matt in her life and with Bonnie still on the fence, she could have used a stable force such as her mother.

More surprising moment: Mason's death, Jenna's stabbing or Elena/Stefan's break-up?
M.L. House: Stelena's break-up. We've come to expect shocking deeds from Katherine and Damon, haven't we? But I totally thought these two were soulmates! I guess we have to remember what producer Julie Plec recently said, though: soulmates don't always end up together.

LJ Gibbs: Jenna's stabbing for sure. I was surprised Damon actually finished off Mason rather than dragging it out an episode or two, but it's still Damon. How shocked can you be? The fact that Katherine not only manipulated Jenna as her spy but orchestrated a near-suicide was as stunning as it was gruesome, however. No wonder Stelena's spooked now.

The Barnacle: Mason's death, purely for how it happened. DAMON REACHED IN AND PULLED HIS HEART OUT!

Has Katherine really won?
M.L. House: Only this battle, but not the war. Vegas has the odds of overall victory on Elena/Salvatores at 7-1.

LJ Gibbs: This week was more of a draw. Sure, she showed the extent of her reach with her mind control over Jenna. Point taken. But with Mason eliminated and the moonstone pilfered, Team Salvatore scored major points too. Can't wait for Round 12 ... especially if it involves Nina Dobrev mauling two people in lingerie simultaneously.

The Barnacle: Yes. What does she care that Mason is dead? She can just move on to Tyler now, and at the expense of Matt's life no less. She'll truly win, however, when she sexes up a broken-hearted Stefan. You read it here first!

What helpful facts will Jeremy next uncover on the Internet?
M.L. House: That Justin Bieber is totally innocent. We knew it!

LJ Gibbs: I don't know, but with this younger's insatiable curiosity and the sprawling expanse that is Internet, the potential is limitless. All he has to do is Bing and decide where to go next.

The Barnacle: That the human head weighs eight pounds and the neighbor of the kid in Jerry Maguire has three rabbits. Watching a DVD on his computer counts as the Internet, right?
