“Devils You Know” is episode four of season three of Marvel’s Agents of S.H.I.E.L.D.
This episode opens in Hollywood in California, and two Inhumans are approached by Alicia, one of the Inhumans S.H.I.E.L.D. originally went up against. She has come to warn them, but before they can do anything, the big, alien looking creature first seen in “Laws of Nature” appears and kills them.
S.H.I.E.L.D. have teamed up with the ATCU – something that doesn’t exactly make everyone happy, on either side, but it’s the will of both directors – and go tracking down a thread that leads to the creature, who is another Inhuman.
In the previous episode, “A Wanted (Inhu)Man”, Hunter managed to get inside the new HYDRA, by killing someone he had thought was his friend in a fight. So he’s getting close to Ward. Of course, Ward knows what Hunter looks like, so this is hardly going to be an amicable, or subtle, meeting.
Simmons is trying to get back to the alien world she was rescued from. Why, she hasn’t explained as yet.
