Argyle

Unlike his shy best friend Jonathan, Argyle is described as a "stoner guy with a deep philosophical vibe", being compared to Jeff Spicoli from Fast Times at Ridgemont High. This is seen throughout the fourth season. Argyle is extremely calm and laid-back; likely a result of him smoking marijuana often. He also seems to panic easily, as when he saved Jonathan, Will, and Mike from Colonel Sullivan's soldiers, he was so distraught at the sight of Agent Harmon mortally wounded and the soldiers wielding rifles, that Argyle momentarily stopped running away to just sit there and wonder in panic. He later did the same when Agent Harmon passed away; Jonathan, Will, and Mike all yelled at him to snap him out of his panicked state.

Argyle is also shown to be a very kind person. He consistently has a good attitude and has no problem giving his friends a ride in his truck.
