To answer that question, all the girls had Joy as their last name. So this episodes proves that they aren't clones. Teeheehee and also that they called Nurse Joy because Joy is their last name, not first.
I mean like how many episodes have Suicune been in the show? Even worst Ash or Brock said nothing about seeing Suicune before. I kinda could have gone without Suicune but at least we see here that some region pokemon don't just stay in the region where they were introduced. Still Suicune could have stay out of this episode but okies.
Teeheehee Also I call next week!!! Teeheehee
