Shame Cilan didn't get that Gyarados.
I didn't like the fact that they never learn they were both Ash's friends... they kept teasing about it with them both being excited to see a Pikachu but then realize it's a different one and being all "of course there's no way he'd be here"... and their mutual "I used to cook for my friends"...
They didn't have to say it from the beginning, but I'd love them to finally introduce themselves in the end of the ep and then go like "wait... you're...!!" and end with that
Oh well, at least we finally got to see a female Pikachu in the anime... only took them about 8 years to do that
