Tousen and aizen.

[Afro Thunda]

This is how Tousen's part will go down. It will turn out that Tousen's friend was killed as a result of one of Aizen's older experiments. Tousen will find this out (somehow) and attack Aizen only to be one-shotted like everyone else who's gone up against him so far.
