Shaw is a S.H.I.E.L.D. agent who took on a deep undercover assignment in Siberia. He was later assigned to the Hub. During the HYDRA Uprising he worked with Agent Victoria Hand to maintain the security of the Hub against HYDRA.
While undercover in Siberia, Agent Shaw collected intelligence on a weapon built by South Ossetian separatists called the Overkill Device. Shaw hid the intel in a capsule stuck deep into his nasal cavity and awaited extraction.
Once in the air, the intel was removed from his nasal cavity by Agent Jemma Simmons utilizing a Paranasal Extraction Unit. Coulson then brought Shaw to the installation known as The Hub for debriefing.
While at the Hub, it was discovered that HYDRA had infiltrated S.H.I.E.L.D., forcing Victoria Hand to trust only five other agents, Shaw included. When Hand gave the order to kill Coulson's Team and Agent John Garrett, Shaw questioned Hand's orders. Hand invoked that the six of them had pledged loyalty to one another and all traitors deserved death.
As everyone in the Hub was corralled to determine their loyalty, Shaw was with Agent Barbour when he told Hand that Agents Jemma Simmons and Antoine Triplett were not accounted for. Hand ordered the two to continue their search. When the two agents were found, Shaw was one of three agents who held them at gunpoint until Hand could test their loyalty.
