Is it just me, or was that a total wasted effort last season? The hype that he was some inhuman stuck in his cocoon, and then once freed, his sister kills him, drops him into the ocean, and he goes back into a cocoon. I know they used him in the framework for the "What If" part, but it should have just been the "Who Cares" part. Maybe they are planning to bring him back in S5 or in Inhumans, not sure. Just seems like that was a waste of screen time, casting, writing, an overall failure in every way.
