** While the huge number of large-scale disasters is pushing it a bit, Seattle is a big city. But, the rare cases and cutting-edge procedures can be {{Justified}}. The hospital is one of the best in the country, and the paramedics and general population know that, so they deliberately bring the hard cases there. They're always performing cutting-edge surgeries because they want to keep their edge and "change the face of medicine".

* Another one concerning Gary Clark from Season 6, how the heck did he get into the operating room where Derrick was? Meredith and one of the nurses were sitting outside the room, so there's no way he could have went in unnoticed.

* How old is Arizona? Seriously, she looks like she's in her early 30s but let's look at the facts. She was made Head of Pediatrics in season 5, and it's treated like an obvious progression so she can't have been exceptionally young for the post -- Maggie is seen as, at 30, very young to be made a Chief of a department. So, Arizona is at least a few years older than that in season 5. Though, it's strongly implied that she became a doctor because her brother died due to lack of Army doctors in the Middle East. They're supposed to be about the same age, although going by Nick's age in season 8, her brother might have been a bit younger and so she might not have gone to medical school right away because logically he needed time after 18 to sign up then serve then die, making her even older. So, say late-30s in season 5. There's also the fact that she's older than Callie, who is said to be an age-appropriate choice for Mark when he's dating Lexie, with Mark being born in 1967 so Arizona must have been born around then, too. Are we supposed to believe she's 50? (Though this would make sense with some of the details she gives of her childhood -- her grandfather serving in World War II means her dad was probably born in the 1940s and given the family then she'd be born less than 30 years later, the masses of homophobia suggests she grew up either a decent length of time ago or somewhere podunk, maybe both, and she'd be going to college during the height of the AIDS crisis which may be, apart from her general characterization as human saccharine, reason why she wants to help treat the African babies, who are often born with HIV/AIDS.) But, really, she doesn't look it at all, and Jessica Capshaw isn't old, either.
