The episode begins with a flashback to Lucy and Joseph finding the Darkhold after years of searching.
Sure enough, they find the book under some layers of dust in this abandoned basement.
Funny thing is, the text appears in English to Lucy and German to Joseph.

But the power is too tempting.
He manages to tell them he put it back right where they found it before dying of ghost-induced fear.
That info hasnt done Lucy much good, however.

Shes able to find the Darkhold again, but apparently the book only reacts to living flesh.
In her ghost state, she finds the words disappearing as quickly as they appear.
Anyway, Coulson wants to talk to Eli again.

Daisy says its better for everyone that way; she clearly still has unresolved guilt issues.
Coulson and May arrive at the prison to transfer custody of Eli to S.H.I.E.L.D.
They attack the S.H.I.E.L.D.
Mack reminds him to focus on the objective.
NEXT: Prison break!
Simmons lie detector test seems to be going well.
The first answer is a funny yes (remember that time she went undercover?
Just then, Mace shows up and asks her to come with him.
It sounds ominous, but in typical Mace fashion, its a bit of a misdirect.
Theyre live in 15.
Robbie disagrees; its actuallyhisresponsibility, and his alone.
This fascinating conversation about two characters differing priorities is quickly interrupted by a ghost attack.
Multiple ghosts, in fact; this is a straight-up monster mash ghost party.
A different ghost manages to infect Mack before getting burnt into oblivion, but its no big deal.
Macks a big boy; he disinfects himself by injecting Fitzs cure straight to his neck.
Now that all these non-Lucy ghosts are dead, I feel better about never trying to learn their names.
The debate between Nadeer and Mace starts off well enough.
Nadeer isnt impressed with Maces background as a hero in Vienna, instead spewing more propaganda about Inhumans.
Eternally unflappable, Mace assures Nadeer (and viewers) that S.H.I.E.L.D.
has everything under control.
Cut to Coulson icing a couple of raging prisoners in the jail cafeteria.
quickly calls Nadeer out on her dog-whistles.
Nadeer isnt fazed, declaring that Mace is clearly not the man for this job.
Coulson demands that Fitz find them another way in the cafeteria as May engages the Watchdogs in hand-to-hand combat.
As she told Mack, she was an extremely capable S.H.I.E.L.D.
agent even before the Quake powers, and now shes proving it.
Her fingers linger over them before she leaves.
After kicking the hell out of the Watchdogs, May reprimands Daisy for acting suicidal.
Daisy says they werent supposed to come back, she didnt ask for that.
What nobody asked for was a prison riot, but its going down anyway.
On their way out, Mack splits off from Eli and Robbie to help out some fellow S.H.I.E.L.D.
He tells Eli to meet S.H.I.E.L.D.
outside while he tends to this business.
Some straight-up office realpolitik going on here.
On the ship, May finally tries to give Daisy a talking-to over her repeated suicidal stunts.
Eventually, May just pulls out the trump card: Lincoln wouldnt want you killing yourself over what happened.
But after May leaves, she does appear on the verge of tears.
That facade is starting to crumble.
The last scene features a secret meeting between two former combatants.
