As Eli Morrow continues to gather his forces, S.H.I.E.L.D. calls in their big guns for the mid-season finale of "Agents of S.H.I.E.L.D." Per Coulson, Director Jeffrey Mace has allowed both Ghost Rider and Quake to participate in this operation, granted that they keep a low profile, and they aren't alone. Coulson also brought in Elena "Yo-Yo" Rodriguez, who proves integral to their mission in a new clip from "The Laws of Inferno Dynamics."

The clip opens with Fitz and Simmons, who try to piece together how Eli Morrow's powers could ever possibly work. Simmons seems to have grown from her experiences with the Inhumans, because she's the first to suggest magic, much to Fitz's disgust. Apparently, the only thing Fitz hates more than magic is clowns.

The scene then cuts to Daisy and Yo-Yo, who join up with Robbie. Together, they've scouted the buildings, and it appears as though Morrow's hired help has retreated inside the building. The three agree that this can't be a good sign, and that turns out to be prophetic. Daisy sends Yo-Yo inside the building for a quick recon mission, but that proves dangerous for the speedy Inhuman. When she steps foot in the hall, she ignites a chain reaction and the walls burst into flame. The clip cuts before revealing Yo-Yo's fate, even as she turns and makes a mad dash for the door.

“The Laws of Inferno Dynamics” will pick up where “The Good Samaritan” left off, in that it will follow Eli’s plan through to completion. The episode in between — “Deals With Our Devils” — focused more on Coulson, Fitz and Robbie, who were stuck between dimensions, and revealed a handful of new clues about the Ghost Rider. While S.H.I.E.L.D. focused on rescuing their own, Eli has had time to regroup and create whatever nefarious device he wanted to in the meantime. Fortunately, it seems Robbie and the Ghost Rider will give him a little trouble along the way.

Called “Ghost Rider’s Last Stand,” “The Laws of Inferno Dynamics” airs on Tuesday, December 6.

Airing Tuesdays at 10 pm ET/PT on ABC, “Marvel’s Agents of S.H.I.E.L.D.” stars Clark Gregg as Agent Phil Coulson, Chloe Bennet as Daisy “Quake” Johnson, Ming-Na Wen as Melinda May, Iain De Caestecker as Leo Fitz, Elizabeth Henstridge as Jemma Simmons, Henry Simmons as Alphonso “Mack” Mackenzie and more.
