Hive can only possess Inhumans.
Still waiting to see Eden Fasi, Druid and Phobos.
Maybe they'll be Season 4.
And because Im a firm believer that the Secret Warriors HAVE to be book accurate, I submit it will either be Joey or Lincoln that bites the dust. Probably Joey - cue Coulson's breakdown about never having worked for them in the first place.
EDIT: I quite liked the "Are you drunk?" ... "I'm Australian. Of course I am".
EDIT 2: The cruelest thing to do is probably to kill Fitz or Simmons. This is a Whedon show ...
