|I kinda hope it's just a possible ending.|
I watched it the second time with the Commentary turned on. Apparently they are shooting for those events to be canon.Jed and his wife said that they tried to setup milestones and scenes that they can hit if the show continues, and while some of the scenes are pretty specific some are left a little vague. However they said even the vague ones they want to hit at some point, though the context in which they occur (or the events leading up to it) might not be what is assumed.
So, if we are to believe the commentary those events will happen one way or another... it's just a matter of time.
Now the question is whether another season (13 episodes) will be enough to reach the beginnings of it. IE, will we have the Kitchen ultimatum scene this season, or further in the future.
