Fair enough. Then I guess the only real open question is what happens to Jesse, especially since Marie knows he's involved.

That's exactly what I've been thinking. 'Granite State' and 'Felina' were an epilogue of sorts. Sure, with 'Ozymandias' it didn't feel like the show had ended, we still wanted more, there were certain questions we needed to have answered, but the actual ending (in a traditional sense) was Ozymandias.
