Okay. If you haven't read the books I might say a few spoiler-y things... but
OMG I think it's KLAUS!
Aaaaaand we open with
being introduced to yet ANOTHER hot vampire.

I'm shocked. There are just not enough hot people on this show.

High school (I often forget that these people don't just go to parties at the Lockwood's mansion, but they actually go to class from time to time)... it seems as though the two girls who were killed in the previous ep are being mourned. I like the continuity. I wouldn't have been surprised if the killings would have never been mentioned again... except I suppose it's meant to torture poor Tyler. Imagine that, a tortured supernatural creature.
Never seen that before.

Tyler. Poor Tyler... someone needs to tell the guy the truth. That it was not his fault.
Hot Vampire from the beginning is keeping Elena in some beautiful country house.

Okay so... kinda like how people don't understand what all the supernaturals see in Bella (you're so dazzling, Edward!) Swan? I'm kind of starting to feel that way about Elena (pouty frown) Gilbert.
Back at the school that people suddenly realized they still need to attend from time to time, they are coming up with a PLAN. To save Elena.

And they have to light candles to do it. Candles. In a classroom. In the middle of the day.
This just seems ridiculous.
But Damon is here to help.

Because. IT'S. ELENA! We must go and save her! She is the O Wanted One. Like... Bella, Sookie, Anita etc... sigh. Getting tired of it.
I will give it to this show, however... they have good tunes.
"Wolf Like Me" by TV on the Radio for when Tyler walks on screen... oh... I SEE WHAT YOU DID THERE.

OMG Caroline, JUST TELL THE POOR GUY. He's breaking my heart.

Nice! You told HIM. I really love that girl this season...
Back in the middle of nowhere... they just happen to have a stately abandoned mansion...

Exposition city. Let's tell the captive EVERYTHING about our plans!
"Rose": We're giving you to this ancient vampire dude name Elijah. He's really old. He's your worst nightmare...
Apparently there are a group of vampires called "The Originals" and these guys are the only ones badass enough to scare the hell out of Katherine (or Katerina Petrova?) Also, there are "doppelgangers"... which sounds really serious. But the thing for me is, the word "doppelganger" has always been kind of silly... like "dingleberry". So the gravity of the situation is a bit lost on me, because I chuckle inside every time someone says the word "doppelganger".
Also... would these 500 year old vampires really be british? Or is that just the easiest foreign accent for American actors to speak...
And why is this guy (hot vampire Trevor) kicking books all over the place??
Seriously, I can't find a sreencap of it, but Trev spends an entire scene explaining his past with "The Originals" while kicking books around a room.
And because we have to pan back to Mystic Falls from time to time...

Awwww... Jeremy & Bonnie are kinda cute.
Bonnie pretty much figures out where Elena is... and even sends her a message via mind-paper (and of course, a candle).
Aaaand she told her dudes where to go to find her.
It's good to be friends with a witch.

Damon & Stefan road trip bonding! This is actually kinda awkward and not really that cool to see these guys drinking blood bags from straws, talking about feelings.
Back at the vacant country mansion, Elijah has finally come onto the scene. I think he might be the only un-hot vampire that this show has ever produced. Actually, he might be kind of hot... it's just that all the other vampires on this show are ridiculously good-looking... so maybe he's just un-hot by comparison.
Elijah? If you were really that old, wouldn't you be shorter?

Come'n show.

Thinking of a strategy, Damon says something like... "we might not come out alive"... (even though we are main characters on this show).
Stefan: "I can't think of a better reason to die"... sigh, oh Stefan.
IT'S. ELENA!
Back in the house Trevor begs for forgiveness from Elijah.

Not gonna happen.
Shit. He killed the newly introduced hot vampire. So long Trev..
And in come Damon & Stefan doing all kinds of swirly fast vampire stuff.
Oooooo... you just pissed off Elijah.

HOLY SHIT DAMON KILLED THAT REALLY OLD DUDE!

And awwww, Damon is so sad cause Elena ran to Stefan. Even though HE was the one who killed the really old dude.

Damon... you can come over to my house anytime you want. And if you kill a vampire (or hell, a spider) with a really big steak, I'll run right up to you and hug you tight. I promise.
Back all safe and sound in Mystic Falls. Time for hugs. And brotherly confessions.

Jeremy... the head-holding embrace is only cool with boyfriends... not bros. You're getting kinda creepy.

Stefan: "I'm sorry I forced you to turn into a vampire that one time. I just wanted my big bro to be with me."
Awwww... brothers love each other!
And poor Tyler. I used to HATE this guy. Now I'm like... come here, let me hug you!

But Caroline hugs him. Yea :-) He's not alone anymore. I like this. I like this a lot.
But we gotta end things with a bang (not a hug), so "Rose" comes around to spook Stefan a bit.

She's all like... "Dude. You've got a real problem... and his name is Klaus."
Klaus. Klaus. Klaus. Klaus... oh yeah, I am so smart.
And Stefan is all like... "huh?"

I cannot tell you how many times I've seen this expression on my boyfriend's face... while talking to him about this show.
But then we go back to Elena's room where Damon proceeds to BREAK MY HEART by professing his love to her (but saying that his bro is the one who deserves her), and then erasing her mind so she'd forget about it.

Damon. Just.
Tear...
On a side note... do eyes really come in that color? Cause... damn.
But the really real end with a bang cliffhanger is...

Elijah is not so dead after all.
Oh. Shit. How does THAT happen?
Does he have one of those Gilbert rings... but for vampires? Like the oldest witch who ever lived made it for him?
Was she black?
~~
Final thoughts:
I'm not sure I caught what the whole "doppelganger" thing is about. Like... there's been others before Katherine? Is this like Winona Ryder/Mina Harker in Dracula?
This show continues to hold my attention like a mofo. There are like, 10 reveals in an episode... where your typical teen drama tends to have one reveal every 10 episodes.
And I'm loving this show because it's fun. I'll watch Boardwalk Empire for the cool stories and character development. I'll watch Mad Men to catch a peek of authenticity and beautiful writing (and beautiful Don Drapers), but I'll watch the Vampire Diaries because it's so. much. fun.
