Bailey-centric episode! With back-story! Yes yes yes!
Cons:
This is such a minor thing, but I needed a tiny bit more build-up to Bailey realizing that she's having a heart-attack at the beginning. As it stands, it's really, really hard to blame the doctors for being hesitant in the beginning. Obviously as it goes on and they continue to ignore her, I no longer have any sympathy for their position. But right at the start, it's hard not to think "horse, not zebra." Maybe if we'd seen just a slight amount of Bailey's symptoms affecting her - like, she says she's nauseated, so can we see her worry she might throw up? I don't know if I'm making any sense with this.
The random woman who Bailey saves and who is next to her in the hospital is fun or whatever, but nothing came of her and she felt rather out of place. I like the idea of Bailey having a blank-slate stranger character to riff off of until some of her friends actually show up at this other hospital. But I wanted a bit more of a payoff.
