"Devils You Know" is the fourth episode of season 3.
Lash is out murdering more Inhumans and S.H.I.E.L.D. is tracking them. The ATCU steps in and helps them take down Frye, a new Inhuman, then claims possession of him. Daisy and Mack are allowed to accompany the transport back to the ATCU facility so they can finally see it. However, Lash attacks them on the way and kills Frye, injuring Mack but sparing Daisy, much to her confusion. While Lash is departing the scene Daisy catches a glimpse of his shadow transforming into the shape of a man.
Meanwhile, Hunter is out for blood and is pulling out all the stops to infiltrate the top ranks of Hydra and get at Ward. May goes back to base to try to warn Colson that Hunter is getting reckless and while there she refuses to talk to Andrew. Coulson doesn't pull back Hunter and he succeeds in getting close enough to meet Ward. However, Ward recognizes him and shows that he has the power to kill Andrew, leaving the option up to May and Hunter; drop their weapons or he'll tell his men to kill Doctor Gardner. Hunter takes a shot at Ward, anyway, and manages to hit him in the shoulder but Ward escapes before Hunter can get a second shot.
