  • Mole in Charge: When he takes over Queenan's unit.
  • Professional Butt-Kisser: How the rest of the cops see him
  • Raised Catholic: Like most Irish-American kids. The Prolonged Prologue has a shot of him serving as an altar boy. note .
  • The Starscream: He ends up betraying and killing Costello after finding out Costello's an FBI informant and was ready to expose him to the feds.
