The speed that Ashi goes from hating Jack to loving him, as well as Jack's transformation from haggard, PTSD madman to normalcy were both way too quick. But, this season is only ten episodes. They just don't have time for long arcs, so I completely understand their decision to speed things up. It sure would be nice if they had two or three seasons to work with.

The only one I really agree with is that it does feel a little forced. I would have preferred implying it at the end of the show or just waiting until the end to have it happen.

Other than that tho, it really isn't a big deal
