Does this bother anyone else

Meredith spent time in Europe after college and only went to medical school when she came back and found out Ellis was sick. And Cristina (No H) is a double doctor. She has an MD and a PhD.

Lose one friend. Lose all friends. Lose yourself.

According to Jo, she got full ride for both college and med school, however those are Ivy League schools and rarely (unless needy, like financial) do you get full scholarships like that. Alex obviously checked up on her and the hospital would too on her educational background, so as a few OP have speculated if her real name is not Jo, did she steal someone's identity or create a new one before she went to school which would mean she
A. married this very abusive man right out of HS and soon after ran away and and went to school, changing her name at the same time.
B. Went to school stole someone's identity and became that person
C. Everything from the story she told Alex is made up (about living in her car, etc)and she conned her way around life
Either ways there are so many holes, things do not add up and I hope they don't turn this into a soap opera moment where we are expected to suspend disbelief.

Camilla makes no sense in this role based on her looks. Very few people are blessed with a perfect smile who grew up on the streets, and interns don't make much, and I doubt she would've splurged on teeth whitening because when you grow up poor, your priorities are different (I say this as someone who lived in a shelter when she was younger). It is possible that her husband did pay for stuff. That said, she probably could've got a lot of financial help for college (she was a ward of the state, I think, so she could've got funding that way). She could've gotten academic scholarships, maybe Mrs. Schmidt put in a good word for her with a foundation that gives bursaries etc. She also could've worked her way through school. I worked my way through university and grad school starting from government housing and ghettos, so its foreseeable that she did too.

26 would be about standard for someone starting med school, because most start college at 18, its 4 years so they're there until they're 22, and med school is 4 years.

Ellis probably wouldn't have been able to fast track because of the rampant sexism holding her back.

If a surgical residency is 5 years, 31 would again be on the right track. What's less believable to me isn't the fact that they're attendings, but that they became department heads so early.

And Cristina was a late started BECAUSE she had ambition. She's referred to herself as a 'double doctor' before, because she went and got a PhD from another school in bio chem, I think, before med school. Meredith was a late started originally because she didn't go into med school right away, but then they bungled that timeline up with the definitely-not-planned-from-the-beginning Maggie introduction.

In regards to the Jo thing, you have to remember that this is the same show that made a stereotype of a drug addict looking like they had to have dreads and had to be covered in tattoos and piercings if they weren't in med school (lexi in the alternate universe vs amelia in real universe) . So their view on a lot of things is pretty warped, lol!

My best guesses are she either found a birth and death certificate and applied for a new SS#. Maybe she had enough training to get through school with high honors. OR she stole a classmates identity and maybe that person died as a Jane Doe.

She's claimed she's put people in the hospital before, so maybe after the abuse, she accidentally killed someone and took her identity (while in college or med school) was as smart as the classmate and thus able to be that person. I would love for that to be the twist. Then she goes to jail and Alex somehow gets off.
