And I believe more strongly than ever that the Pidgey, Hoothoot and Salamence were Brandon's. My reasoning is simple: Noland owned all the Pokémon at the Battle Factory, same for Lucy at the Battle Pike. Brandon owns the Pidgey, Hoothoot and Salamence, he just allows them to live in the Pyramid outside of their Poké Balls.
Actually, I don't think those ruins were part of the pyramid. Judging from what Jindai's judge said before taking off, the Battle Pyramid seems to settle wherever there's ruins worth exploring (Jindai took off because I think the judge said there were some new ruins discovered). And to answer an earlier question, no, those ruins are not part of the pyramid. I think it should be pretty obvious, with the way the pyramid had a flat base, and those ruins were underground.
And still on the subject of the ruins, Musashi pointed out something funny at the end of the episode. There was a legend behind those ruins that supposedly concerned Houou (and Rocket Dan, as well as Satoshi, went through the ruins to find Houou). As they were blasting off, Musashi seemed to make the connection that Houou, as well as Poppo, Hoho, and Bomander (the latter three all having attacked them in the ruins), are Pokemon that start with the Japanese syllable ホ "ho" (ボ "bo" and ポ "po" is kinda the same thing, which explains Poppo and Bomander). Don't know why the ruins would have a theme of a Japanese letter, but whatever. Speaking of Musashi, earlier in the episode, she picks up a Muchul statue which she thought was adorable. Nice bit of continuity, there.
Anyway, ever since the Kekking episode was announced as taking place after this, this episode was a friggin huge relief. A loss in the battle means no rushed Brain battle against a legendary within a single episode. And hey, if Jindai's off to explore more ruins, maybe there's still hope that he'll have Regice and Registeel when Satoshi re-challenges him. Though, I gotta say it was a disappointment that Jindai treated Regirock as an average Pokemon.... I don't even think Haruka's Pokemon Zukan, nor any of the characters, made mention of the fact that it's legendary (let alone be astounded that Jindai was able to catch one). It's also worth noting that the battle was stated as being one-on-one, so any theories that the legendary Pokemon would get leeway and be treated like Akane's Miltank were wrong.
Possessed Satoshi was also a bit of a let down.... I was hoping for Matsumoto Rica to talk in her sinister Bakura voice, and maybe using "ore-sama" for first-person as a nod towards her other role. Instead, when Satoshi's possessed, he seems to take on the spirit's voice instead of the spirit communicating through Satoshi's voice. The spirit seemed to be a male seiyuu, and he used "ware" for first-person. It was still pretty cool, just not quite what I was expecting. And even though Pikachu did shock Satoshi out of it, it wasn't near as much of a cop-out as it could've been (some speculated he'd be shocked immediately.... in this case, though, Satoshi was possessed for a good while, and in the end, Satoshi had to struggle to get out his command to shock him).
Those saying Satoshi wasn't in control for this battle are a little off. He did have a little control at times (those scenes where Satoshi's floating in some abyss and sees Jukain, whom he shouts commands to. He also manages to ward off the spirit momentarily).... it makes sense, really. The spirit relies on a skilled trainer to battle for him, but still manages to use his own, underhanded tactics in the middle of it all. BTW, for those wondering, the spirit had a reason to fight in a Brain battle. Jindai agreed that if he lost, he'd surrender any Pokemon he has (notice that when Satoshi first got possessed, he tried to take Haruka's Pokemon, stating that all the Pokemon are his or something to that effect). Having a lot to gain (and lose), he was desperate to get Pikachu in there after Jukain went down, even though the battle was officially over at that point.
The battle itself was pretty sweet, too. It's not often you get to see the afforementioned underhanded tactics, like using a judge for a shield, of all things (I'm surprised he wasn't disqualified for that, but I guess they never exactly state rules on the Pokemon's boundaries. Pokemon seem to cross those white lines on the arena floor all the time). Lock-on looked pretty spiffy, as well (reminds me a little of Sui Fong's skill in Bleach, in which a mark is left on the opponent's body to make it a vulnerable target).
