Bloody fun episode, Ash identified all the Kanto starters. Shauna is cute and Trevor is moe as ****. Tierno is bro and is voice by Katsu Anri.
Sycamore does an introduction prior to the start of the OP, apparently similar to the game.
After the girls say UMI DA! and meets with Sycamore, Ash reports to Sycamore about Mega Lucario.
There is a camp and Ash and company are in Team Froakie and get their own cabin. After Clemont mentions that Ash and Serena went to camp, focus is on Serena's face regarding that detail. Later, after meeting Tierno and its dancing style battle with Squirtle, they are introduced to Shauna, who remembers Serena from her Pokevision video. She fangirls over her and her Fennekin and also show them her Bulbasaur video. She shows them her somewhat vain Bulbasaur. Later, Trevor comes along, tired, apparently having the same constitution as Clemont. He also recalls Serean from her Pokevision video. Seeing this attention, Serena grabs her bangs and blushes, leading to Tierno to dance and call her cute. Before they go outside, Tierno mentions that Ash is from Kanto, and here he mentions that his dream is to be a pokemon master. As they leave, Serena is left alone wondering about "dreams".
They later battle to earn some apparent points, but not to the point of fainting. Apparently it is only those who draw "first blood" or gets the first hit. Serena is a total newb at this of course and is very hesitant in doing moves, Chespin is BTFO by Charmander, and Ash, well, is astounded by Squirtle's unorthodox dance-battle moves, as it nearly gets a hit before Froakie can use Water Pulse (Froakie used it before but was dodged by the dancing Squritle). However, it was an assured hit (its claws/fingers were on Froakie's neck) so Tierno wins. There is also something about Diantha related to the camp or something. They later eat dinner, where Clemont shows off his bag.
Later, Serena is alone at the docks and marvels at Ash's dream of becoming a Pokemon Master, and apparently wonders about dreams herself.
For those who were wondering about Serena's character and apparent "goal-lessness". Now is the hour of reckoning. I believe this is an arc dedicated to her. Also, Pikachu is in the title screen for some reason.
