[spoiler alert] Cristina & Dixon scene (Season 4-17 & Season 5-10)

I want to hear everyone's opinion about that.

"-Is your stuttering pathological and persistent or is it occasional and stress-related? -I don't stutter. -I had pathological stuttering as a child, but it can be treated with rigorous speech therapy. -Yes, ma'am. Thank you."

Cristina's response was a bit meaningful in that scene. Was it an expression of dyslexia symptoms mentioned in s4? I don't know what the intent of the script was, but I have a feeling Sandra meant something by her performance.
