Fitz and Hunter listen patiently in this photo. What are Bobbi and Mack planning that they're keeping from Hunter? It's clearly something that will affect the entire team.

Marvel's Agents of S.H.I.E.L.D. is back for Season 3, starring Brett Dalton as Grant Ward, Elizabeth Henstridge as Agent Jemma Simmons, Iain De Caestecker as Agent Leo Fitz, Ming-Na Wen as Agent Melinda May, Chloe Bennet as Agent Daisy Johnson, Clark Gregg as Director Phil Coulson, Nick Blood as Agent Lance Hunter, Adrianne Palicki as Agent Bobbi Morse, Henry Simmons as Agent Alphonso “Mack” MacKenzie and Luke Mitchell as Lincoln Campbell.

Agent Fitz struggled with, but overcame the damage to his brain after suffering oxygen deprivation at the hands of Ward. He was the last person to see Simmons. Will he blame himself for her mysterious disappearance?

Fitz will not stop until he discovers the truth behind Simmons' disappearance. Can he find some answers regarding the massive alien Kree monolith? Who will he turn to for help, Lady Sif perhaps?

Fitz and the team are determined to save Simmons on Marvel's Agents of S.H.I.E.L.D. "Purpose in the Machine" is the second episode of the show's third season.

We've seen how determined Fitz is to find Simmons. He reaches out to an Asgardian, Elliot Randolph, for help unlocking the Kree monolith's secrets. Will the Professor give us a clue where Simmons ended up?

Professor Randolph leads Fitz and the team to a mysterious bunker. Is this machine Kree or Asgardian? Can they use it to locate Simmons?

Looks like Fitz is beginning to flip switches and press buttons. Are you sure that's a good idea Leo?

Is Fitz asking for Mack's help here, or is the big guy questioning the mission? Mack has proven himself consistently level-headed. Isn't is possible they might open a portal allowing Kree warriors to cross through?

Is Fitz taking a moment to consider the repercussions of using the machine? Is his quest for Simmons worth unleashing more aliens into our world? Remember, something was chasing Simmons on that planet.

Fitz patiently helps Simmons deal with the trauma of her time on the other planet.

Before Fitz and Simmons can take the next step in their relationship, S.H.I.E.L.D. deals with a shocking truth about the ATCU.
