Edit: Yep. And they're spectacular.
Spoiler
OP indicates Episode 2 won't be China's only appearance and also hints at Sei's return (via silhouette! YUS). Also Mirai is hinted to be the next Gunpla Idol.
Junya finally appears... seems jerky. Fumina's jelly level is really spiking and yay the return of Gyanko, Shimon and Suga. The latter fishes. The new Gunpla are finished after much quarreling and napping. We get a Nemesis European Junior Champ named err Lucas? ... we're going to actually go to World level now? Sakai is once again a threat, so long after his debut. The theory about BBG being perma-RG mode seems confirmed. Wilfrid also recognizes the BBG.
