Continuity mistake: When the Watchdogs destroy the government facility near the start of the episode, 6 shots of Nitramene are fired onto the building's exterior before it implodes. But moments later when Coulson calls Mack, he (Coulson) is watching the news report of the event, and the 6 shots of Nitramene are nowhere to be seen.

Maria Hill: What does S.H.I.E.L.D. Stand for, Agent Ward?
Grant Ward: Strategic Homeland Intervention, Enforcement and Logistics Division.

Question: Is there any explanation to how Agent Coulson is alive even after Loki killed him in The Avengers?
Chosen answer: Coulson believes he was resuscitated then sent to Tahiti to recuperate. "A magical place," he calls it. But in the "Agents of S.H.I.E.L.D." episode "The Magical Place", Coulson, through a mind-reading machine, learns that he was treated by S.H.I.E.L.D. and a fake memory of Tahiti was placed as a "mask" of sorts over the painful memory of the operation, which involved a drug seemingly of alien origin to repair the damage, coupled with a lot of morally dubious surgery.
