Solid episode this time. It was so entertaining that I didn't even notice it was ending haha. And it's nice seeing evil!Team Rocket doing their stuff.
Another thing I like is that it seems this is Ash's first meeting with the Zarger dude. I wonder if he'll be some sort of replacement for Ghetsis since Team Plasma seems it won't be used.
Anyway, the things that bugged me is how it's possible have a space-time warp to ancient times and how convenient is that the paleontologist dude just happened to find the Tirtouga he had befriended. Just minor issues, though.
And the episode has extra points with me for not coming with a "Paleontologist Connousier Cilan" hehe
