Lexie/Grey's Goof
I don;t know if this has been talked about (I'm sorry if it has) but I noticed an error in facts when it comes to Lexie's age. I hate when writers reveal a fact about a chaacter and then forget and change it in a future episode. Here are two exchanges from different seasons of Grey's Anatomy.
Season 5/Episode 12
Mark: You're Meredith Grey's little sister, you are forbidden fruit, you are 25, you're a fetus.
Lexie: 24, I skipped 3rd grade.
Season 7/Episode 14
Christina: There's no way she's 20. Maybe 26, 27.
Lexie: I'm 27.
So in two years she's aged three. I get that it's not a big deal and that the move was likely made to make Lexie closer to Chyler's real age (28) but it's still annoying.
