Eliza served her purpose. She came to be a love interest for Arizona. IF Callie comes back then Shonda doesn't wanna hear that Arizona never got the chance to move on. It's not just Calzona fans who didn't like her. Alot of general Grey's fans didn't like her either. Just look at the comments in this thread.
She came in on this high horse that her way was the ONLY way. She didn't try to compromise or want to tweak her method at all. I doubt she's in S14. Other than off screen still sexing Arizona down. I'm not sorry to see her go. They didn't have any chemistry. Better yet she and Penny can get together. I couldn't stand her either. I'm glad Eliza is fired! I'm sure Marika is a nice person. But her character was wooden. It was like watching a mannequin. Just no.
Just bring back Callie, Cristina, Teddy, and Addison. Characters who were amazing.
