Radcliffe responded by calling AIDA and ordering her to initiate something called the Sunset Protocol.
Who could it be?
A prime suspect is Mack, who is finally consummating his relationship with Yo-Yo.

Almost the moment after they have sex, Mack gets a mysterious text and starts lacing up his boots.
Hes not going on the new mission, but wont say where he is going.
Yo-Yo is understandably confused.
The mission itself is rather complicated.
General Talbot doesnt like this plan he insists that everything at S.H.I.E.L.D.
The general isnt going down easy.
Talbot is serious, though he even thinks all Inhuman assets should be transferred to a secure military facility.
That way, Nadeer wont be able to find them if she tries to subpoena S.H.I.E.L.D.
agents a pretty likely outcome if she catches them trying to install surveillance equipment.
Talbot walks away mad.
She asks Fitz if AIDA knew what she was doing when she betrayed them.
He tells her she did it to save him and Coulson, which is how youre built.
In the middle of all this, we get a nice FitzSimmons scene.
Simmons asks Fitz if hell come along on the mission with them.
He tells her hes too busy with work (a.k.a.
But for now, theyve both got tasks to complete.
Mace tries to comfort her and reminds her that he knows what its like to live a double life.
On the other side of the operation, Yo-Yo has questions for Coulson about Mack.
If only the mission went as well as that conversation.
Her position is bolstered even further when Coulson and Yo-Yo fail in their mission.
Its not a good look for Mace and Talbot.
Back at base, Talbot is understandably furious at being proven right.
Now Nadeer has ammo to initiate a full investigation of S.H.I.E.L.D.
He accuses Talbot of being the mole, which is patently the wrong move.
A very angry Talbot reminds Coulson that he believed in S.H.I.E.L.D.
when no one else did, and that the organization only exists today because of him.
Now hes wondering if he should retract that support.
While this has been going on, the real May has been desperately trying to escape AIDAs clutches.
As soon as she does, she runs out of her containment pod … and straight into AIDA.
AIDA has super strength and uses it to throw May through a door and against a wall.
After racing up several flights of stairs, May thinks shes found an escape.
Shes confronted by AIDA again, and once again May manages to out-fight the robot.
But when she kicks AIDA off a balcony, shes surprised to see her fade into data.
AIDA then reappears behind May and informs her that shes still inside a simulation!
Radcliffe figured out that the best way to keep May occupied was to give her something to fight.
NEXT: The second LMD
Meanwhile, LMD May has questions of her own.
LMD May has a better lead, anyhow.
The LMD May confronts Radcliffe at his lab and demands to know what he did to her.
She knows shes the spy, but Radcliffes programming prevents her from telling Coulson or anyone else the truth.
Theres no time to find out, either, as FitzSimmons arrive with Coulson and a squad of S.H.I.E.L.D.
agents to arrest Radcliffe.
They take him away, but without finding human May or the new AIDA replacement.
That hits a lightbulb for Fitz.
He takes a guards gun and shoots Radcliffe in the end revealing that HE is the second LMD.
Im gonna need assistance, Fitz declares.
The real human Radcliffe is with Nadeer.
As for the human May, shes caught in a new simulation.
In this version, though, May did save the Inhuman girl.
Which means she probably wont want to wake up for awhile.
It was one plot twist after another in this episode.
