This episode certainly had enough reveals and plot twists to make the wait worth it.
The episode picks up almost exactly where the midseason cliffhanger left off.
AIDA has just killed S.H.I.E.L.D.

Now, AIDA goes about covering up her treachery best as she can, removing her blood-stained blazer.
They all know letting AIDA read it was a mistake in and of itself.
(Like, say,Avengers: Age of Ultron, perhaps?)
Robots arent the only things capable of betraying humans, of course.
Luckily for him, Vijay Nadeer finds himself on a comfortable bed in a fancy house.
When he goes outside, he finds his sister waiting for him on the lawn with breakfast.
Simmons isnt done with him yet.
Well, actually, Mace seems content with the good PR from Daisys public addition to the team.
The two of them just seem to have different priorities.
They set off with Simmons to rescue him.
Coulson, Fitz, and Radcliffe are otherwise occupied.
agent shooting her has no effect at all.
She throws Fitz through a glass door, where he finds Nathansons body and realizes AIDAs betrayal.
AIDA gets away for now, though without the Darkhold in tow.
Luckily, the SHIELD agents are kicking their rescue plan into overdrive.
Simmons disguises herself as a consultant seeking a meeting with the senator.
Unfortunately, Nadeers aide sees right through her and calls the armed henchmen to ask what they do.
Simmons subdues the guy and takes his phone to trace the call to Vijays location.
The fateful moment has come for Vijay.
The gunmen emerge from the trees to kill him.
In Ellens mind, Terrigenesis is merely the next phase in the alien plan to contaminate humanity.
Vijay is able to talk her down, however, by arguing that hes not an Inhuman.
Ellen has her goons stand down, for now.
Meanwhile, AIDA has come back to find the Darkhold and is soon confronted by Coulson and May.
Her plan is revealed in the next scene, when Coulson and the May LMD are imprisoned together.
She then successfully retrieves the book.
Mack once again reiterates his knowledge of robot movies in which the robots always turn on humans.
His paranoia isnt skin deep.
AIDA is unable to escape before Fitz takes back command of the base.
He locks her out of the system, which stops her from being able to leave.
AIDA admits she feels regret about killing Nathanson, even though Radcliffe notes she wasnt programmed to feel regret.
She responds that the Darkhold has changed her, shown her regret and desire.
Before AIDA can elaborate any more, Mack sneaks up from behind and decapitates her.
Roll credits, he adds, fist-bumping Yo-Yo.
That leaves Vijay in the company of the armed gunmen.
This, naturally, does not end well.
One of them moves to attack him, at which point Vijay reveals his Inhuman power of super-speed.
He disarms and takes down the goons, but some shots are fired and that draws Maces attention.
The three of them arrive with Senator Nadeer just as Vijay finishes off the goons.
Simmons and Ellen then make a run at convince him to go with each of them.
Poisoned by his sisters paranoia, however, Vijay still seems convinced that S.H.I.E.L.D.
just wants to use him as a weapon.
He ultimately decides to go with his sister.
Simmons wants to go after him, but Mace tells her that Vijay made his choice.
It was, of course, the wrong choice.
While theyre on a getaway helicopter, Ellen kills Vijay herself with a shot to the chest.
The look in his eyes is devastating, right before he collapses in her arms.
She does seem to have regained absolute control over her little gangster squad here, though.
Never question me again, she tells them, covered in her brothers blood.
Mack demonstrates his extensive knowledge of robot movies to Yo-Yo, while Fitz quietly mourns AIDA.
As LMD May tells Coulson, at least now they know who the real enemy is.
Apparently everything the old AIDA did was by Radcliffes order.
He got one little taste of the book, and hes salivating for more.
Or maybe something like Resurrection Man, where he always comes back with a new power?
That would be nice, considering this show already has one speedster.
One episode into this LMD arc, and the main AIDA is already dead.
