As I recall this is the second appearance of Jynx in purple.
Back on topic, I haven't seen either version of this episode yet (I did see its neighboring episodes in Japanese though) and I have to say it's nice to see that the ban on Jynx has been lifted. I'm assuming Jynx keeps its archived voices from back in its appearances in its older color.
Also, if you've checked Pocketmonsters.net, when you hover over this episode title, a caption appeared reading, "Woot, a Jynx. Another banned episode?" (may not be the exact words, but it should be close) LOL! I don't know if the sites up right now though, but I thought it was funny.
