Grey's Anatomy Season 9, Episode 23: "Readiness Is All" was a difficult one for many of the docs at Grey Sloan Memorial Hospital. That's what happens when it gets to be season finale time! But which actress had a scene so difficult, she almost cried between takes?

Camilla Luddington (Jo)! And yes, it was during her heartbreaking fight with Alex.

A fan tweeted at Camilla after the episode, asking, "Was it really hard to act that super tense scene with Justin Chambers?"

Camilla replied, "Yes. I wanted to cry between takes."

Given that the scene in question involved Alex confronting Jo about beating Jason half to death, we can't blame Camilla. There were a lot of emotions in that scene. Jo admitted yet another terrible thing that happened in her past. She talked about how she thinks Alex is a really good guy, and then was filled with worry that he might hate her now — until he sorta kinda confessed to loving her, in a very Alex-like way.

We were in tears, and we didn't have to act it out!

Catch the Grey’s Anatomy Season 9 finale on Thursday, May 16, 2013, at 9 p.m. ET/PT on ABC.
