I thought the beasts and Naruto did had some secret strategy going on that would allow him to reclaim all the beasts or something. They didn't specify that exactly, but that's what I thought their little meeting was actually about aside from learning names.
Madara's situation is just BS. Where did he even learn that jutsu handsign from? Why didn't he do that until now? Kabuto could have reclaimed control over Madara at any time so it'd make sense to do it as soon as possible as far as risks are concerned.
It freaks me out whenever I see Kabuto just standing there. It feels like he could move at any moment.
