>>106550273Marinette and eventually Adrien meet Master Fu and he starts translating the book Gabriel had, eventually leading to him giving them both potions to unlock power up forms of which they've since used 2.
Hawkmoth's identity is officially revealed, though it's not like season 1 didn't make it extremely obvious. It's also revealed exactly what he wants the Miraculous for and why.
It's revealed how many Miraculous Fu has, as well as 3 more characters getting to become heroes using the Fox Turtle and Bee, but they don't get to keep them permanently and only have it given to them if they really need the help. So far they were only in a handful of episodes.
All of the other Kwami are introduced, but most of them are only in a single episode so far.
Hawkmoth also gets another ally using the Peacock, but they were only in the season 2 finale so far.
Two alternate love interests are added for both Marinette and Adrien each, but they don't show up much.
But these are maybe....1/4 of the season. The rest is typical Monster of the week stuff like season 1. The only thing that changes is that Chloe isn't the cause of most of the akuma's this season, and they only show the school if it's important to that episode rather than have the obligatory class scene in almost every episode like season 1.
It's better....but only slightly.
