First of all... I spent the first half of episode one wondering why Cali was crying so much. Had Arizona died? Did I miss something? Everything else (mostly) made sense, although it seemed strange that Meredith and Derek constantly referred to vague things like, "Are you sure you want to do this today?" or "It's almost 5:00!" I hate it when writer's write a script that way, intentionally keeping something obviously vague.
When they killed George (way back a million seasons ago), it was a much more elegant script-writing, I'm just saying. I mean, I didn't see that coming, during the episode, and after the reveal it made you think, "Wait! That was under my nose the whole time and I didn't even see it!" But with this new vagueness, it constantly poked at me that I wasn't in on the joke, which was actually rather irritating.
But I digress...
So because I kept feeling like I was missing why Cali was crying (it gave me this nagging sense that I'd missed an episode), I actually Googled "Did Arizona die?" thinking that maybe I'd forgotten a part of the finale from last season.
And... if you've seen this episode... you'll know what I found... a headline that basically said something to the effect of, "Arizona loses a leg and Mark Sloane dies." And it's like... "Wait!!! That was NOT was I was searching for!! Way to spoil the ending!"
So... yes I shouldn't have been Googling while I was watching a show and expected not to see any spoilers, but... would it have been too much to ask to let things play out in order so I don't feel like I missed something? It sucked the drama right out of the episode because I felt like I was coming into the season mid-stride and spent half the time trying to orient myself.
Then I watched this week's episode and it suddenly all made sense. This was where I thought we were going to start last week... at the plane crash and what happened afterwards. I might even have to go back and watch last week's now because that's what feels like should happen next in the sequence of things. Why are you constantly rearranging what feels normal to me, Shonda Rhimes?
