Tommy Lonegan is the proprietor of the Combat Zone, formerly known as the Orpheum Theater of Boston prior to the Great War. A deal made with a local raider gang has brought this dapper business-ghoul steady profits, yet has made his fighting club, the Combat Zone, less welcoming to the general public. He doesn't mind the fact that the gang's nature drives away potential customers, because they still continue to be loyal patrons, that are willing to place their bets on the party most likely to win.
Tommy Lonegan cooperates with the Institute's Synth Retention Bureau, providing tips on escaped synths in return for caps. He is the current holder of Cait's employment contract, and is compliant with the fact that he will have to let her go, in the event that he loses his current clientele, as he is concerned with the state of her chem addiction.
