The mazo pulls in the bijuu, but the hachibi might have done that to save bee and leave a portion of his chakra behind to keep bee alive.Was just going to make a thread about this. Except against Sasuke the tentacle was actually the clone wasn't it? Is it possible that the real Bee and Gyuki transformed into one of its tails? I hate cliffhangers, I guess we'll find out in about 3 weeks....
Merry Christmas
