The premiere
So, I had some thoughts:
The baby's name: I'm half expecting them to be like "haha, we were just messing with you it's not harriette" next episode, or at very least they'll do the weird thing where they call the baby by its middle name like they do with a lot of the kids. I don't see them calling a baby harriette, at very least. I do like the hyphenated name and scene that accompanied it. Katherine needs to learn boundaries and that set that up nicely.
Now the big stuff...
Jo/Deluca/Alex: I'm kind of sad that I'm seeing people blaming Jo for this and saying it's her fault. That's ridiculous. The only one at fault here is Alex, who acted on impulse without taking a second to understand the situation. Jo was giggling when she was on the bed, so at best, if they were about to have sex, that implies she was probably on board. So I have trouble believing that Alex actually thought DeLuca was forcing himself on her. If Alex had known straight out that she was drunk and thus couldn't consent (because I don't think he was aware beforehand to my memory, but I could be wrong) then yes, but what it seemed like he was reacting to was that he walked in on a hook up, not assault. if that's the case, that means his actions were from his own aggression and poor judgement. I love Alex, but he is 100% in the wrong here, not Andrew, not Jo. Alex punched first, and then didn't even bother to ask later.
Mer: I also have seen people saying Mer shouldn't have said anything and all that, and I feel like this is a great case of Mer being damned if she does, damned if she doesn't both on the show and in the viewer's perception. Mer HAD to tell. When you're in a job with a duty to report, you're supposed to report even if you just have a suspicion with reason. I work with kids and teens, and if I even suspect something I'm duty bound to report it. If it's found out later that I didn't report a suspicion and it was something that needed legal intervention I can face legal consequences, lose my job etc. Doctors have a similar duty to report. She had to do it. People seem to be saying "she should've stayed loyal!" But if she had and not shared, people would've been saying "she should've told! Where's the realism in her risking her job and future!". People on the show are mad that she didn't tell soon enough, and I'm sure there will be people who are mad that she told at all, but at the end of the day,they are not interns/residents anymore, and the fact that she did tell and actually do the right thing shows me that maybe, juuuusssstt maybe, they'll actually have Meredith grow more this season. And the little scene at the end with Mer and Alex was good, and it shows me that they're both growing up. The original 2 left who were the biggest bailers when they were younger are actually facing up to their problems. If the situation wasn't so *beep* it would be great haha
Jo/Alex: really quick thought, but did anyone get serious S2 Mer/Der vibes from that "you're incapable of this" speech from Alex to Jo tonight? It reminded me of when Derek was all the sudden furious at Mer when she started seeing Finn and he called her a whole. It's not a great moment for either Alex or Derek but it was an interesting callback.
