As the final season of Lost builds rapidly to a climax, the show nevertheless takes the time to give us a secondary pre-climax climax—in the form of a nice, swift kick between the legs.

Now, let’s break form and get right to talking about the end of this episode, because that’s what’s on everyone’s mind.  Given the structure and pacing of the season so far, I was expecting an important character to die this week.  I was not expecting three (possibly four) to die.  It was rough and brutal, it was sad and heartbreaking, and it did two very important things: it raised the stakes for the viewer, and it finally drew the line in the sand that the Man in Black is evil, evil, evil.  Heck, he’s Evil with a capital E.

“It makes Hurley cry” can probably be used as a new litmus test.

After taking years to finally reunite, Desmond and Penny got their happy ending (albeit temporarily).  Jin and Sun, also apart for years, finally reunite as well, but their happiness is cut tragically short.  This was like Juliet all over again, times two, with a dash of worse thrown in as well.  It was a legitimately sad ending for two very likable characters who had gone through such hardships to be with each other again, and it was handled beautifully.

As quick and sudden as it was, I think Sayid’s death was handled well, too.  Martyrdom was pretty much the only logical way for his character arc to end, and given the tension going on with the episode, it felt very fitting that, in the midst of Jack and Sawyer’s rivalry and bickering, someone else would need to make the snap decision to save the day.  Or, well, to salvage what could possibly be salvaged of the worst day ever.  Also: “It’s going to be you, Jack.”  Excellent and ominous last words.

Lapidus is still unaccounted for.  But hey, Jin survived an exploding freighter, so I think Lapidus can survive a bulkhead to the face.  But I’ll get more into my theory on that later.

There was a lot of action in this episode, especially in the final scenes.  If I have one complaint, it’s that Kate seemed like she got shot pretty bad, and then didn’t even get any first aid, but in the aftermath of everyone else dying, her gunshot wound got turned almost instantly into an afterthought.  Don’t get me wrong; I’m all about not overloading the audience with tension, but her actually getting shot and the moments after were done so well that I thought that was going to be the episode’s main “Oh Shit!” moment.  You’d think that escaping from a sinking submarine and having to share oxygen with someone while getting inundated with seawater would make things worse after getting shot in the torso.

Honestly, though, that’s little more than a nitpick.  Just about everything else about this episode put it on par with Season Finale quality drama and suspense.  There were some awesome character moments, especially from Jack, Sawyer, and the Man in Black (I’m glad to see, in this episode especially, Terry O’Quinn’s diverging take on both the Man and Black and John Locke).

Over in flash-sideways land, Jack is still in his literal “I want to fix people” state that he was stuck in before, pretty much up to the point when he got Juliet killed.  This is Classic Jack at his refreshed peak, and the juxtaposition between him and Locke in the old days of the original timeline (as well as him and Not!Locke in the original timeline) is actually kind of poetic.

Of course, now the characters in the flash-sideways timeline are starting to see and recognize all the weird life-altering coincidences surrounding Oceanic 815.  What does all that portend in a universe without the Island?  Hard to say, but clearly it’s going to mean something.

And speaking of things with greater meaning, this is why I don’t think Frank Lapidus is dead: with Widmore’s submarine well and sunk, the only real way for the characters to escape the Island is the Ajira plane.  I expect we’ll see Mr. Lapidus rising from the briny deep to save our castaways sooner than you can say, “Screw you, Man in Black, for killing off half the main cast, you dick.”
