This show keeps surprising me, and I was very happy to have a Kree take part in the episode. Thanks to him, we got even more information on the Inhumans, the Terrigan mist, and even references to a Kree city. The show barely touched upon the whole nitrogen plot point, pretty much dropping it completely after the Kree was found; I guess he was using the nitrogen to keep himself undercover as a human-looking figure (still doesn’t explain the height/size difference from other Kree we’ve seen, but I can look past that).
