While on the phone with Frank in The Departed (2006), Sullivan shares his disapproval about Costello's crew pushing Queenan to his death. Frank defends the action stating that one person had to die and disregards Dignam and his departure. Sullivan is upset that he no longer has access to the information that Queenan had:
Sullivan: He put in his papers, Frank.He left. I don't know where he is.
Frank: Don't get your balls in an uproar, Collie. That Irish pissant... he's so hot for me, we give him a whiff of my ass, he'll crawl right in it. Let's give him a whiff.
If Dignam is not of Irish descent, then who is Frank referring to with the Irish derogatory term?
