I feel like episode 8 was a return to form for me. I like Pierre but the episodes were pretty weak and felt too fillery.
It was great to have some context on Yggdrasil's influence. Some people like Gorou(that's what I'm calling him)are happy they fixed it up, while Kaito and Mai were effected pretty heavily by their appearance. Kaito's one track mind suddenly has context and understand him a bit more. It will definitely add some weight to him and Takatora meeting or him finding out Mitsuzane's origins.
Speaking of Mitsuzane, he's turning into an interesting character. The fact that he is regularly using his power to get what he wants makes him incredibly two faced. And it all boils down to Mai. The fact that they fight together so much now will probably mean him turning on Kouta down the road. Getting Sayaka vibes from him just based on my current place in Madoka.
Man, Mango arms is one badass suit, huge improvement over Banana power. I'm still not feeling neither the banana spear and how he uses it. It just bothers me he's using it like a sword, might as well have given him one.
