- "Semtex. The whole place is rigged to blow."
"There's enough explosive to bring down the whole mountain on top of us." - ―John Garrett and Leo Fitz
Semtex is a plastic explosive used in commercial blasting, demolition and in certain military applications.
History
- "There's no time to search the whole compound. Maybe we can take some Semtex, use it on the doors."
- ―John Garrett
After Coulson's Team infiltrated a secret compound known as The Guest House, aided by Agent John Garrett, they found a timer connected to a vast amount of Semtex scattered all over the bunker, and enough to bring down the mountain on top of the complex.
While Agents Phil Coulson and Leo Fitz were looking for the drugs needed to save Skye's life, Agents Garrett and Grant Ward unsuccessfully searched for the detonator or a way to deactivate the explosives, so they used some of the explosive to blow the bulletproof glass doors that were closed upon their entrance.
When the timer went to zero, the Semtex exploded, burying The Guest House under 100 feet of rock, and Agents Coulson and Garrett, the last ones in exiting the complex, got to board on The Bus just in time to avoid the effects of the explosion.[1]
