S02E19 "Putting Your Hoof Down"
Things she could be saying in this image:
1: EX-keeyuze me?!
3: Would you care to repeat that?!
4: I beg your pardon?!
Additions to this list are welcome! Also, look at each of these and tell me if you actually hear her saying them. Oh let me make that easier. Tell me if you DON'T hear her saying them.
