Two weeks ago on Grey's, the big event of the season (at least so far) involved one ambulance crashing into another just outside the hospital. The accident has left at least one person dead, a white supremacist paramedic in surgery, another paramedic still hanging upside down with an oxygen tank valve stuck in his chest, and the other driver in surgery for a brain tumor, which is what caused her to have a seizure and wreck the ambulance, and a patient that was inside one of the ambulances in surgery to remove his sternum due to an infection he got after having heart surgery. The one and only patient that we met at Seattle Grace that wasn't in the ambulance crash was Nick (played by Seth Green) who after having a tumor removed from his neck now has his corroded artery exposed. At the end of the episode as Lexie was putting new bandages over the artery it exploded and was squirting blood all over the place. I have to admit that ever since seeing that I now have a fear that my own corroded artery is going to burst for no reason.

This week's Grey's Anatomy was a must-see special event, so special in fact that it is two parts. The main event is an ambulance crashing into another ambulance just outside the hospital seriously injuring the patients, paramedics and drivers inside.

Before we get to the main event though, we begin with Cristina dancing and having a great 'ole morning. Then, Meredith comes in with her typical negative energy and tries to ruin it by babbling about how she's having sex with Derek while he is dating other people. Finally after Cristina tells her to loosen up she starts dancing too. Now with Cristina and Meredith in good spirits who is the next negative person to try to ruin a good morning? Izzie, come on down! After seeing them dancing she runs to George and complains about Cristina and Meredith's love affair and wonders why she and George aren't the ones dancing. She decides to go to work early to get on a kick ass cardio surgery to piss off Cristina.

"There comes a point in your life when you're officially an adult," says Meredith as this episode begins. Meredith then reminds us that despite our privileges as adults - voting, drinking, etc. - we really are still the same as we were in high school, whether that be the band geek or jock or prom queen. As the episode goes on we start to find out what clique each of the docs fell into in high school, and believe me you'll be surprised by some of them.

After their affair and the separation of George and Callie, Izzie and George finally get to have the perfect hot (and sweaty) sex they've been waiting for. There's just one problem; the sex isn't hot or perfect, in fact the sex sucks. On the other hand, Meredith and Derek continue (for what seems like the billionth time) having break up sex, which just so happens to be perfect and hot. Derek has an affair going on though... with the Chief. Obviously not a sexual affair, but it is definitely a love affair, at least in the way that the Chief loves Derek for doing all his dirty work for him such as getting his clothes dry-cleaned, eating dinner and watching movies together every night. Sloane makes fun of Derek the whole episode telling him that he's "dating the Chief."

No, despite the episode title the docs will not be kung fu fighting. What does happen this episode is a skydiving accident in which a man freefalls 12,000 feet, and survives; two women fight to hold onto a wedding dress to win a $100,000 wedding package; an awake open heart surgery; and the men of Seattle Grace plan a mystery "gentlemen's evening."

We begin with Meredith laying on the bed rattling off her problems to Cristina who is playing therapist for the day. Cristina tells Meredith she has too many problems and diagnoses her with severe abandonment issues. Meredith says that's crap. We then move onto the Chief who now has his own camper parked next to Derek's camper. They have breakfast and coffee together. I think Meredith better watch out, the Chief is moving in on her man. Jokes aside, while having breakfast the Chief suggests to Derek that they have a "gentlemen's evening." Derek has no idea what the Chief means by "gentlemen's evening" but goes along with it anyway. George slept at the hospital last night, so Izzie wakes him up with some talk about wanting to have 'perfect sex' tonight. Derek and Sloane welcome Hahn ("the new Burke"), who is surprised by everyone's good looks. She asks the Chief if he hires on looks alone. Not to be too harsh, but if that were the case I'm afraid she wouldn't be working at Seattle Grace. Derek tells Sloane about the Chief's "gentlemen's evening" plans, and Sloane is also puzzled by what it means.

Unlike most shows who use Halloween as an excuse to just go crazy, Grey's Anatomy actually did their Halloween episode right. To be honest, I was a little nervous at what direction the episode was going to take when in the beginning Meredith's very own dead corpse is talking to her. Fortunately, that was only a dream and things got back to normal, well as normal as things can get at Seattle Grace.

The love triangle: A week of waiting to find out how Callie would react to George and Izzie's fling nearly killed me. Finally, it's time. It's the morning after and Callie is still sitting, in deep thought not speaking to George. He's begging her to just say something. She finally speaks. "I forgive you," she tells him. He's confused. She tells him that they took vows, so she forgives him. Next we see George rushing around in a tizzy to find Izzie. When he finally finds her it seems it's too late, Callie has found her first. George observes the two from a distance, hiding behind something. Callie tells Izzie to be in the cafeteria at noon, just her and Izzie. Izzie is pretty much scared shitless at this point. She thinks Callie wants to fight her, as does everyone else. And, by everyone else, I really mean everyone else - every single staff member in the hospital finds out about it.

As the infamous Grey's Anatomy elevator is going up it seems Alex's attraction for Lexie is doing the same. The two share a glance and a smile before all the other annoying little interns crowd their way into the elevator. The interns are abuzz over George, apparently someone forgot to mention to them that he is a repeat intern. They can't believe how much he knows already. Next up on the elevator is Meredith, Derek, and Cristina. Meredith and Derek awkwardly greet each other which Cristina takes note of. She can't believe they are still 'doing it' and Meredith hasn't told her. Izzie, meanwhile, is watching all the elevators waiting to pounce on the one with George. As soon as George steps off the elevator Izzie pounces asking what happened (with asking for a divorce from Callie). George just shakes his head as Callie is right behind him.

This week's episode is all about addiction. Everyone is addicted to something. We learn that it's the high we're chasing. The high is what makes everything else fade away.

We begin with George expressing how much he loves Izzie. So much so that he has finally made the decision to end his marriage to Callie. Meanwhile, Derek and Meredith are busy getting it on. Apparently having sex, and lots of it, are part of their break-up. Meredith comments that it's the best break-up ever, Derek wonders why they didn't break-up a long time ago. Cristina is still dealing with the wedding mess, specifically all the wedding presents. She digs through them wildly opening them all, but really doesn't care what they are.

The long awaited season 4 premiere of Grey’s Anatomy begins with a classic sunrise over the city of Seattle, the space needle and of course, narration by Meredith Grey. Our favorite interns are now residents and they are off to a bustling start giving orders and laying down the rules for their interns. Including George O’Malley, I still can’t believe he has to be an intern again and Lexie Grey who is one of Cristina’s lucky interns. Izzie’s interns
