BackgroundAfter the Terrigen Mist was unleashed worldwide , more Inhumans started to arise. However, Inhuman killer Lash killed a majority of the population and inflicted human casualties, causing S.H.I.E.L.D. and the Advanced Threat Containment Unit to ally against him.
During the Attack on Dwight Frye, which resulted in the death of Frye, S.H.I.E.L.D. agent Daisy Johnson witnessed Lash transform into a normal human. She, with the help of Alphonso Mackenzie, later came up with a theory that Lash was embedded in the ATCU and that operative Luther Banks was the Inhuman hunter.
Daisy Johnson, Alphonso Mackenzie and Lance Hunter found Luther Banks in a parking lot and tailed him undercover in a van. Tired of waiting, Hunter masked himself with a handkerchief and shot Banks unconscious with an I.C.E.R.. Hunter brought the agent to the van and the team observed him.
The team sent a blood sample of Banks to Jemma Simmons at the Playground, to test the sample for Inhuman markers. Johnson, Mackenzie and Hunter left Banks unconscious in his car and drove to Endotex Labs, the location where Banks was scheduled to arrive. The trio infiltrated the lab with a D.W.A.R.F. and found Phil Coulson in the building with Rosalind Price. Simmons called back to confirm that Banks was not Inhuman, proving Johnson's theory to be incorrect.
After Johnson's incorrect theory, Andrew Garner would be revealed to be the Inhuman killer Lash, with Melinda May interrogating Werner von Strucker during a scuffle in Lisbon, Portugal.When this was revealed to S.H.I.E.L.D., a battle ensued as they learned that Garner had kidnapped May when she confronted him over his killings.
