It was rather unexpected to see Szayel appear in this. He seemed to be forgotten. I hope this fight is gonna end soon. As much as I like Mayuri (one of the most interesting characters in this series), it starts to feel dragged a bit. Although it wasn't completely pointless as we learned something about Nemu during this fight. Hope Mayuri can revive her.
Dam just like I thought, Nemu sacrificed herself to win the fight. I really didn't that would happen when this fight began, I thought for sure Mayuri would die.
But Nemu is not totally dead, Mayuri saved her brain, so end of the series, I expect Nemu maybe as a infant or a child to be back.
I was confused though when Espada number 8 came back, I knew it was just an hallucination, I mean we know he is in hell, but still a nice surprise.
