I'm torn about this episode, which I'm pretty certain I've said almost every episode this season.
On one hand, I thought it was really well shot and acted, I like the different types of shots like the "security" footage. I liked seeing Bailey, Arizona and Jo together (although Bailey was acting kind of strange to me in the beginning), and I admit to tearing up at the end after the baby was born. But, it definitely an odd choice for the mid-season premiere. I follow the spoilers closely so I knew exactly what we were going to see going into it, but still it felt odd and very non like Grey's. They even played around with the episode numbers this year so this was definitely chosen as the premiere. Yes, they did something similar last year but they had Denzel Washington to hype it up, plus while it was a "stand-alone" Meredith episode it still Grey-Sloan focused.
Other thoughts, I liked Jo in this episode but was disappointed they didn't use it to reveal something useful and interesting about her history but rather have her tell the patient she robbed a store with an ex-boyfriend? Seemed like they could have used that moment for something far more revealing about Jo.
Perhaps I was just getting bored/restless, but I didn't really understand the convo in the car at the end with Jo having to throw up. I was actually just wondering if they wrote in something around Camilla's morning sickness because I didn't really get it. I should probably go back and watch again.
In a nutshell, its pretty much what I've to expect from Grey's....a fine, maybe even nice standalone episode but did nothing to advance any of the pending storylines.
