What would be a fun twist would be if Castiel died like x times, and went into the empty, the vesion of cas that came back could be the last saved copy. And perhaps the entity would find that jack reached out to all the copies of castiel, and that  could piss him off. I like the empty as a main baddie.

That would be one case, the other case could be that god did indeed have access to the empty and brought cas and other beings back by bargaining with the entity each time
