Everyone has a secret. Dr Andrew Garner has a huge one. So does Agent May. The same secret, actually. Jemma had some, but she gave Fitz her magic i-Phone. So this episode is for telling some secrets, and keeping others.
Lincoln has been secretly in touch with Daisy, Mack secretly meets with Lincoln. To discuss- May and Andrew's secret, actually.
Secrets which are soon out in the open. But suddenly May and Andrew go missing. And, it seems they had a secret even before all of the fun stuff with "Lash" started.
This episode acts a mainly a Denouement, resolving many things that had been left open ended. Joey Gutierrez (Juan Pablo Raba) is back, the metal-melting inhuman. This is the first we've seen him, and we hear about a new facility, "The Cocoon". And Daisy confronts Rosalind (Constance Zimmer of the X-files episode "First Person Shooter") about keeping Inhumans on Ice. Both have strong feelings about it, Daisy against it, Rosalind supporting it as a "life saving measure". But I still question her motives.
Ironically, Freezing Inhumans might be a good short-term solution for a certain problem. And all of the story arcs that I mentioned in the last episode are now merging back into one arc - And we get to see Inhuman vs Inhuman. Will Lincoln keep a lid on it, or will he take revenge? Speaking of Revenge, Ward has focused his Attention on one certain aspect of SHIELD. Is Rosalind in on it? Because Hydra ain't dead yet. Let's not forget about Will Daniels, the "Astronaut" left on Jemma's Sand Planet. And Fitz uncovers something about who actually sent that team through the portal.
