Just finished watching this ep. A few preliminary thoughts:
-You know that attack that we all thought was most likely Shock Wave? Well, we were WRONG! Surprised? I was. It was actually Water Pulse. This proves that unlike Surf, Water Pulse does NOT require the Pokemon to be in water in order for it to work.
-And remember the purple rings around Seviper's and Cacnea's eyes? As I suspected from how Grovyle looked in the previous episode, they were confused--due to the aforementioned Water Pulse.
-Some nice animation overall in this ep, I paricularly liked the part where Pikachu repeatedly jumped back to avoid Seviper's Poison Tail...reminded me of the Bellossom episode when Pikachu battled Victreebel and did about the same thing.
-And yes, the Linoone belongs to that kid.
