Sheridan’s second, played by co-star Mick O'Rourke, is a supporting character in "Family Limitation". He works for Irish-American gangster Charlie Sheridan and accompanies him to a meeting with rival Johnny Torrio. They bring two other guards with them. Sheridan has the guards search Torrio and his men, Jimmy Darmody and Al Capone, before the meeting. Sheridan and his second are seated opposite Torrio and his men for the meeting while the guards stand behind them. One of the guards notices a knife in Jimmy's boot during the meeting and draws his gun until Jimmy has been disarmed by Sheridan's second. After the meeting the coat checker hands weapons to Darmody and Capone and they murder Sheridan, his second and both guards.
