When S.H.I.E.L.D. Agents Phil Coulson, John Garrett, Grant Ward and Leo Fitz approached the entrance of the bunker, Alpha and Beta were suspicious of them, because there was not a scheduled visit for the following weeks, so they tried following the protocol of these situations, asking a password to the approaching agents.
The agents hacked their way inside the bunker, and both guards acknowledged how good they were. When they reached the inside doors, the guards and the agents began a gunfight.
Alpha was shot by Agent Ward, and later died of his wounds, not without warning Agent Coulson about the timer for the self-destruction mechanism of the Guest House.
When Raina was presented with a handful of vials marked GH by John Garrett in the Barbershop Headquarters, she asked to see the facility from where he got them. He told her that a "couple of security knuckleheads hit the kill switch."
