"You have a brilliant mind, Sameen, and you're very gifted but you'll never be a doctor."
As a doctor, Sameen Shaw was exceptional.
I think one of the things fanon forgets about Shaw is how smart Shaw is, she pretends to be a 'grunt' but she isn't. She loves to tease the whole team about being nerds but she's as much as a nerd as anyone in the team. Her skill set is broad and varied but one thing we have canonical proof of is Shaw was a brilliant doctor, more than brilliant she was gifted.
You don't just say that to anyone.
Unfortunately, her brusque bedside manner didn't play well with the patients and with time I sort of understood why Shaw was reprimanded but at the same time, I look at other popular male doctors who are as or worse than Shaw.
If Shaw did her residency in Seattle Grace I think she'd fit with Cristina Yang, and I'm wondering now if Shaw had a Bailey as a mentor would things have gone differently for Shaw because I think Shaw responds well to authority figures who pushed her to be better but also rein her in when she needs to be reined in.
If things had continued I think Shaw would do well as a surgeon maybe, even a neurosurgeon or maybe she'd be a brilliant trauma surgeon because of how well she can operate under pressure. The higher the stakes, the better Shaw shines.
But I wonder if the lifestyle would suit her down the road, we know that Shaw also likes work that gives her a bit of adrenaline, maybe in her off days (when she has them) she'd be the type to do extreme sports.
If she did join the navy so the Navy will pay for her medical school maybe she'd be deployed overseas right in the thick of the action.
Unfortunately, Shaw didn't have a mentor who could have guided her properly and just when her star was rising, she was booted out of the medical program and her life changed forever.
