[Loki, Barton, Selvig and the other S.H.I.E.L.D personnel are in the parking lot of the facility]
Clint Barton: Need these vehicles.
[referring to Loki]
Agent Maria Hill: Who's that?
Clint Barton: They didn't tell me.
[Hill looks suspiciously at them as they get into the truck and turns to leave, as she's walking away Fury shouts through the walkie talkie]
Nick Fury: Hill, do you copy? Barton has turned...
[suddenly Hill turns to shoot at Barton but Barton is already pointing his gun at her and starts shooting, he moves the drivers seat of the truck and drives off as Hill keeps shooting]
Nick Fury: He's got the Tesseract! Track it down!
[Hill gets into a truck and follows after Barton's truck]
[after the research facility has collapsed, Fury and Hill try to chase after Loki but fail to catch him escaping with the briefcase containing the Tesseract; talking through their walkie talkie's]
Agent Phil Coulson: Director? Director Fury, do you copy?
Nick Fury: The Tesseract is with the hostile force. I have men down. Hill?
Agent Maria Hill:A lot of men still under, don't know how many survivors.
Nick Fury: Sound the general call, I want every living soul not needing rescue looking for that briefcase.
Agent Maria Hill: Roger that.
Nick Fury: Coulson, get back to base. This is a level seven. As of right now, we are at war.
Agent Phil Coulson: What do we do?
