I don't really like this chapter because it is so predictable. Obviously Aizen was behind it. He is this manga's only villain(besides Gin and Tousen) as of now. I was hoping there would be a little surprise in store, but I guess not. It wasn't a bad chapter, but I just feel that Bleach's story is becoming too limited.
If Aizen is the only villain and from what we see now in the present they are about to fight him then technically either Aizen will escape or he will win. You can guess how things are going to go.
