Japanese Episode Discussion Thread

The manga adaptation follows the movie very closely so if you haven't read my summary of that then you should go ahead and do that now. Everything below assumes you've already done so.
During the "World of Pokemon" segment there's this group shot of our heroes with all their pokemon out...including Hinoyakoma. Who's still a Yayakoma in the TV series at this point. While movies have spoiled pokemon evolutions in the U.S. before (I remember Kids' WB!'s airing of "Destiny Deoxys" spoiling a bunch of evolutions / captures that hadn't happened yet) I think this is the first time something like this has happened in the Japanese version.
The pokemon used in the battle between Carnet and Ganpi - a battle we first found out about through the movie's soundtrack - is Mega Sirnight and Mega Hassamu. Carnet's pokemon wins. Also, the music used - which will be Track 7 "Carnet vs. Ganpi" on said soundtrack - is actually just the Gym Battle music from Diamond & Pearl, of all things. Weird.
Ayaka, in addition to having a Mega Absol, also battles with a male Kaenjishi and a male Nyaonyx. I also don't remember Ayaka actually having any speaking parts but I could be mistaken.
Almost all our heroes' pokemon get to battle at one point or another in this movie. Satoshi uses his Keromatsu a few times, his Luchabre during the battle against Ayaka (and then it's used a lot to help him fly at various points during the rest of the movie), Serena's Fokko and Citron's Harimaron battle against Riot's Gekkouga...even Eureka's Dedenne gets a chance to help. The only pokemon who aren't used in this film are Satoshi's Hinoyakoma, Citron's Horubbi, and Musashi's Bakeccha.
Throughout the first two thirds of the movie or so you can see the Steels' Hitotsuki hovering around in the background / foreground, watching our heroes.
Satoshi, Serena, Citron, and Eureka all wear a change of clothes during a scene on a ferry. Citron and Eureka have matching hoodies.
Uschi is exactly as useless a character as you'd imagine. He has only one line.
In the shopping center, Serena and Eureka take Diancie shopping and try on a number of outfits.
I don't think there's a single hand-drawn image of Xerneas in the entire movie. Every time you see the deer pokemon it's rendered with CG and sometimes it looks really, really bad. Oddly enough the same thing doesn't happen with Yveltal.
I don't think Yveltal's signature attack "Death Wing" is named once in the movie.
OK, now on to the part not covered by the manga adaptation that ran in CoroCoro Comics:
Diancie Mega Evolves into Mega Diancie and creates a Sacred Diamond to use as a shield to protect her and the others from an oncoming Death Wing attack. The diamond disintegrates from the force of the attack. A shocked Yveltal is about to try again when Millis' and Algus' airship comes out of the clouds and fires a volley of missiles at the legendary pokemon! Yveltal safely bursts out of the huge cloud of smoke caused by all the explosions and attacks the cockpit of the plane with its talons. It then uses Death Wing on the duo, sending the plane crashing into the lake below. Yveltal turns back to Satoshi and his friends and fires off another Death Wing attack, but this time a beam from the distance intercepts the attack! It's Xerneas!
So, the big showdown between Xerneas and Yveltal...doesn't happen. Xerneas just sort of looks at Yveltal, soothes its heart with its powers, and convinces it to stop its rampage. All without words. Yveltal flies away, the end, most anti-climatic ending ever.
Our heroes breathe a sigh of relief until they notice that Pikachu's starting to turn into stone just like the others! Citron figures out that its tail must have brushed up against Yveltal's Death Wing at some point and that it's going to lose its life soon as well! Satoshi and everyone else cries and it's this big dramatic thing but Xerneas steps in like two seconds after Pikachu turns and uses its Fairy Aura to bring it back to life.
Next, Xerneas turns into a tree. Everyone worries that it's dead, but Xerneas tells them not to think of this as its death; think of it as the "dawn of birth" and the "beginning of hope." Xerneas then uses its power to restore the forest and all the living things in it back to life.
When Riot and Marilyn turn back to normal, Marilyn kisses Riot on his cheek, much to his surprise.
Later, we see Mega Diancie back at the Diamond Ore Kingdom making a new Sacred Diamond. The kingdom is saved! Diancie thanks Satoshi and everyone for all their help. Eureka's Dedenne pops out of her pochet with the diamond that Diancie had given to Eureka earlier in the movie; it looks like it didn't disappear like all the others! Our heroes return the diamond to Diancie, saying that it's a symbol of their friendship, and Diancie says she'll take good care of it. The movie ends with the camera zooming into the diamond, revealing a Mega Evolution symbol.
During the end credits we find out what happens to the thieves who were after Diancie. Millis and Algus are working at a chocolatier (Algus has a problem eating the free samples!) while Marilyn works at a clothing store. Riot shows up in the store with a nice suit and goes up to Marilyn, gets down on one knee, and presents her with an engagement ring. Marilyn smiles.

So basically, Xerneas vs. Yveltal doesn't happen, Xerneas turns into a tree, Diancie basically created its own Mega Stone, and Riot and Marilyn are a thing now because reasons. Still, it was an entertaining movie; it moves at a good enough pace without any of the scenes overstaying their welcome, everyone gets a chance to contribute to the plot (even the Rocket-Dan!), the scenery and music are top notch. I think people are going to like this one even without a big climatic battle at the end.

As for the teaser for next year's movie:

We see Primal Groudon and Primal Kyogre let out a roar before we see a splash of text announcing that the next XY movie will hit theaters summer 2015.

I've said this elsewhere but I'll say it here too; these teasers serve as a means to announce that a new movie is coming out, that's it. There is absolutely no reason any of us should assume that the next movie is going to actually feature any of the pokemon in that appear in the teaser.
