While watching Iron Man 3 with my family on Boxing day something that I didn't pay that much attention to during my other viewings caught my sights. When Killian is describing Extremis to Pepper he shows her that in the Human brain there is an empty slot. The slot can be utilized to rewrite the genetic code of a human being. To put it in Killians words "we were destined to be upgraded". Now here comes the juicy part. The Celestials (which may or may not exist in the MCU) basically endowed humanity with the ability to gain superhuman abilities whether it be from exposure to radiation of from the creation of a splinter species like Mutants and Inhumans. Now the Inhumans were created due to the Kree (who we know exist in the MCU) meddling with early Humans DNA and mutating them into a different species called Inhumans. The only reason they did this is because the genetic potential that the Celestials invested in the Humans had caught their eyes as they could be easily mutated and turned into super soldiers for the Kree. Now to recap. Killian states that human beings have an empty slot in their brains which can be accessed to rewrite genetic code and mutate human beings i.e see Extremis and Centipede. In the comics the Celestials gifted human beings with the genetic potential to be easily influenced by change and mutate from all sorts of stimuli like radiation or the Super Soldier Serum. Millions of years ago the Kree experimented on humanity due to their genetic potential spawning the Inhumans.
Now lets talk about the current MCU. In Agents of Shield Coulsons team has already encountered a man with Pyrokinetic abilities which they theories he could have developed due to a nuclear meltdown of a near by power station. And we know that Blizzard, specifically the second will appear in the 12th episode of AoS 'Seeds'. Now this is only a theory but I think that Scorch and Blizzard are both Inhumans. Now I'm not jumping to conclusions because in the comics currently Blizzard has been revealed to be an Inhuman and Scorch's comic book counterpart Tommy Ng is a mutant. Now we all know that a common theory is that Marvel Studios are going to use Inhumans to get past the whole Mutant debacle and the perfect way to do this I think is to introduce them in AoS. The Centipede storyline seems to be coming to a close and I think it would be great if the new storyline is dealing with the emergence of Inhumans and stopping people from using them for their own personal gain. In the episode Blizzard is showing up Ian Quinn from the Asset is also appearing. Now we know he's at odds with SHIELD and believes in freedom while he thinks SHIELD restricts it as they have power over everyone. Maybe hes trying to amass an army of superpowered individuals to take on SHIELD?
Any way that's a bit of topic. So essentially if the Inhumans are introduced in Agents of Shield then it wouldn't be as difficult to just have Quicksilver and Scarlet Witch show up in Age of Ultron. Then you can jump start an Inhumans movie in Phase 3 having Quciksliver and SW appear init so they don't just disappear from the MCU until Avengers 3. Any way what do you guys think?
