Oh crud croissants, there's a Shanghai special dropping before season 4 itself? I did not even realize! If this leads to any revealed details about ongoing arcs... Granted, Shanghai very much does not=Lhasa, but given past patterns *cough*, eeeeeek! I'm probably way off, and it'll be on a level with New York for content. Probably. There *has* been mention of a new Miraculous wielder in China, via the showrunners, and I can picture a Liiri-esque reveal. But...

As to the actual season 4, I'll take summer/soon as possible and hopeful, and roll with that. I've seen three episode titles, and one suggests mayhem with a character season 3 suggested was out of the picture, one makes me reeeeeally wonder, and the third could be a bottle episode.

Also, thank you for all the info! :D
