Jerry, a security worker for the DHARMA Initiative, was dancing and flirting with Rosie, who had brought him brownies, while he was on duty at a security center. The two were interrupted by a distraught Phil, who scolded Jerry for being distracted. Soon afterward, they notice that due to Jerry's distraction, a drunken Horace Goodspeed had stumbled upon the sonic fence, and was blowing up trees with sticks of dynamite. Fearful of what the head of security, James LaFleur, would do to them when he found out about their leniency, they traveled to his house, waking him up and taking him to the scene. ("LaFleur")
Jerry and his companion Phil, brownie eating 1970s hippies, seem to be references to Phil Lesh and Jerry Garcia of The Grateful Dead.
In the casting call, Jerry was described as "Any ethnicity, mid-20s to mid-30s. A bad boy. Dangerous, charming and always up for a good time. Works in corporate security; can be serious and tough when he needs to be."
