Summer of Discovery! serves as the setup for a mini-arc in which Ash & Co. take part in a summer camp run by Professor Sycamore. Meeting new friends Tierno, Shauna, and Trevor, the two friend groups are designated to different teams and are poised to discover more about themselves and their Pokemon.
This episode keeps it simple, introducing the camp, posing the prospect of being inducted into the 'Summer Camp Hall of Fame', and most importantly, setting up Serena's future ambitions. Serena has basically been a groupie throughout the saga so far, so it is about time that she got a goal for herself. What that goal is exactly is left to be determined in this story arc, it seems. Tierno, Shauna, and Trevor are fine so far--not much to complain about or gaud over. They each have discernible personality traits and goals and whatnot. Good on them.
The episode set the arc up nicely, but because it is an exposition-heavy episode it is pretty tame--which is understandable. Team Rocket seems to be staying out of the way for now, so that's good (for both our heroes and the audience). One little qualm: the characters definitely need to blink more. Throughout this episode they looked like a bunch of Wide-Eyed Willies.
Grade:
B
Side Note: Awful quote! This one left a bad taste in my mouth. Thanks, dub writers!
Ash (explaining to Prof. Sycamore about his experience with Korrina and her Mega Lucario): Mega Evolution is as cool as it gets. Everything powers up, including the strength of their moves. It's awesome how strong they get.
