SPOILER ALERT: If you haven't seen Agents of S.H.I.E.L.D. Season 2 Episode 7: "The Writing on the Wall" and don't want to know what happens until you can get to it, don't read any further.
Last night, Director Coulson finally solved the riddle of the "map" he had been trying so desperately to piece together. It is, apparently, a city. All this time, Coulson had been attempting to draw the map two dimensionally. Last night, he realized it was a three dimensional map and a former agent of S.H.I.E.L.D. had pieced together the entire thing.
Now, what city?
It could be Atlantis. Prince Namor has been an Avenger. But, his rights are probably still owned by Universal Pictures; although, they have never done anything with the franchise. Maybe they have reverted back to Marvel Studios? If so, we may be setting up an encounter with the King of the Seas.
Is it Wundagore? Would Marvel introduce a character like The High Evolutionary and his New Immortals in a television show like Agents of S.H.I.E.L.D.? If so, it would be a major surprise as that particular group has never been mentioned in the Marvel Cinematic Universe - no hints anywhere.
It has been widely speculated that Marvel really, really, really wants to be able to use the X-Men and all the wondrous "talents" and abilities and minor characters available to that "species" of humans. There are hundreds of thousands of people walking around the Marvel Universe who have just a minor ability that has manifested and would make an interesting addition to their Studio world without upsetting the primary characters (Iron Man, Thor, Captain America, Black Widow, Hawkeye, Hulk, etc.).
But, they can't. Marvel and Fox are not on good terms. Marvel and Fox are on terrible terms. In fact, Marvel is actively killing off Fox-owned characters in the Comics Universe and has tied Fox's hands in regards to marketing and merchandising characters for which Fox owns the movie rights.
But, Fox is adamant they will not give the X-Men back to Marvel. They'll bury the franchise in Fantastic Four mediocrity before they'd do that.
So, what does Marvel do?
They turn to another group that has, to date, never really been explored. The Inhumans. Terrigen Mists give them their powers. Everyone has different results from exposure to the mists so, there ya go.
And, Marvel has more control over who gets exposed to the Terrigen Mists and who has access to those mists. And, who wants access to those mists.
My guess: Attilan. Marvel could be going to introduce the Inhumans in Agents of S.H.I.E.L.D. And, we could already have a couple of them on the show - one of them is one of the show's stars: Skye. And, I'm willing to bet her crazy, "monster" dad, "The Doctor", is Black Bolt's twisted, insane brother, Mad Maximus.
This would make sense. Max is a member of the royal family so would be a very important member of the group. He is also wont to wander off on his own and create immense mischief (think Loki - only darker and meaner).
The primary Inhumans are Black Bolt - king of the Inhumans; Medusa, his sister; Karnak; Gorgon; Triton; Crystal; Maximus the Mad; and the canine, Lockjaw. Most of these will be more like Tony Stark and Steve Rogers - they won't deign to stroll over to the television side.
But, Max? And, what a coup for Kyle MacLachlan: He gets to be the Robert Downey, Jr. (Tony Stark / Iron Man) of the Inhumans. He will set the stage for, not only the movie, but also for how the Inhumans are perceived by the movie-going populace.
Also, Skye was found in Southeast Asia. The Inhumans were said to live in the Himalayas which is not far from there.
Skye will not be one of the primary members of the Royal Family. She is the daughter of a prince, though, so will have some importance. But, not enough so she would be removed from Agents of S.H.I.E.L.D. She would still be a viable character on the television series.
A secondary bonus of all this is Marvel's release of the Inhumans Movie (mark your calendars: November 2, 2018) will point back to Agents of S.H.I.E.L.D. All you geeks who have been watching the series can throw out that almighty, "I told you so!" when the Inhumans are referenced back to a story line that's been ongoing.
It'll draw viewers to the series. And, probably positively impact all of their television offerings.
