Non-Action Guy: For the most part, Greg is either in the command truck or negotiating with subjects , and focuses on the commanding the team and the larger picture. However, when push comes to shove, Greg can hold his own, even though he isn't in Ed or Sam's league.
What the Hell, Hero?: He was called out on two occasions by Ed and Jules for putting himself in danger, exposing himself when confronting a subject and for not calling for backup.
Cold Sniper: Compared to Sam, Ed is the stoic and colder officer, and he's portrayed at this... before spending much of Season One stoically dealing with a Heroic BSOD.
Heroic BSOD: In the pilot episode, he has one when he thought he had killed the hostage taker's son who had ran into the line of fire just as Ed pulled the trigger. The effects of this remain a long time.
In "Broken Peace", when he was forced to shoot and kill an 18-year-old girl trying to kill her abusive father (who had taken her mother hostage).
The Stoic: for the most part, this is his role. He's the only member of Team One who can beat a polygraph because no matter what, his reactions are controlled.
Not So Stoic: When someone hurts his family or his team, he becomes this.
Stepford Smiler: Sam and Natalie point this out to him in "Blue on Blue," though he already seems well aware that he uses humor as a defense mechanism.
