Next Tuesday's episode of Marvel's Agents of S.H.I.E.L.D. will see the series conclude its current "LMD "Arc with a fiery end. In last week's episode, "The Return," viewers got to see Aida's reaction to getting the one thing she'd dreamed of -- a chance at being human. Unfortunately for Fitz and the rest of the S.H.I.E.L.D team, things didn't end so well.

In the first clip released for the fourth season finale, Fitz (Iain De Caestecker) and Simmons (Elizabeth Henstridge) pose the very question: how does one kill someone that is both human and Inhuman?

Little do they know the answer to their question may lie in Gabriel Luna's Ghost Rider, who is set to make his return to the series for the finale. Here's the official synopsis:
