For 90% this episode is just like it's sister episode, which was aired as the series finale. But right at the end of the ep they made a few changes. I don't think that these changes are very critical for an eventuality of a season three, but it's slightly better then the original one.
I like the way the producers kept open a mission for Jake and Chavez to save their friend. But if there is going to be a season 3, the main story would still have to be the 2nd Civil War. And the fight of Jericho against the ASA, because its surrounded, with Maj. Beck as their leader.
