*WARNING: SPOILERS FOR AGENTS OF SHIELD , CIVIL WAR , AND JESSICA JONES IN ARTICLE: READ AT YOUR OWN RISK*
In Marvel's Cinematic Universe it's all connected, and even though the Sokovia Accords are going to affect Agents of SHIELD just as it has Civil War, there is another tie in that seems to be under the radar. When Howard Stark's car is ran off the road by Bucky, a briefcase full of packets of blue liquid is stolen from his trunk. What was that strange blue substance in the back of one Howard Stark's vehicle ?
How about a briefcase full of Kree blood packets ? I know what your thinking, isn't that a form of super-soldier serum there, wouldn't it be a new batch of hero making hooch ? Well, let's take a little look-see at some facts:
-In The First Avenger, Steve Rogers had to be hit with vita-rays to activate the serum. Dr. Erskine said that the vita ray treatment was needed for it to work.
-In Civil War, the super-soldiers are pumped directly via I.V. pump. No vita-ray treatment at all. Just fill 'em up and send 'em off.
-In Agents of SHIELD, the serum is directly pumped into Skye (a.k.a. Daisy), Coulson, and others and is referred to as GH, or Growth Hormone, which is later revealed to be Kree Blood, via the T.A.H.I.T.I. Project, also in , Agents of SHIELD, we find out that the Kree were responsible for the creation of the Inhumans.
From the marvelcinematicuniverse.wikia.com article on Project TAHITI:
Project T.A.H.I.T.I. was located within the Guest House, guarded by Alpha and Beta. Inside the Guest House was a room labelled T.A.H.I.T.I. that contained a decaying Kree corpse being drained of its bodily fluids into multiple vials; each vial was labelled with different numbers for several serums but all with GH as the prefix, including GH.211, GH.289, GH.317, GH.319, GH.324 and GH.325. GH.325 has the effect of completely regenerating cellular tissue and implanting fragments of cellular memory of the host to the receiver.
-In Jessica Jones, Jessica was treated by a company called IGH, or in other words Inhuman Growth Hormone
Now in Civil War, the Russian super-soldiers display greater than human strength, reflexes and durability, and if we look at Jessica Jones, after her treatment after a horrendous car accident that killed her family , Jessica demonstrated superhuman capabilities of strength, stamina, and agility that increased as she got older.
Again, Jessica was treated by the IGH company , which also paid all of her medical bills, and during that time period if it figures at the same time that the briefcase was taken from Howard Stark, the organization behind IGH, the Russian super-soldiers and funding and access for Coulson and Fury to build T.A.H.I.T.I. would be the Hydra-infiltrated-SHIELD.
So it is all connected, it's in the blood.
