Everyone goes to Jeremiah's house later for reception where Lt. Green (Terrence Howard) briefs his partner, Fowler (Josh Charles), on the Mercer brothers before joining. All wards of the state, the four brothers, currently minus Angel ([linknm0879085]), were raised and adopted by Evelyn herself after she failed to find them appropriate homes elsewhere. Bobby, the oldest brother, holds a reputation as a heavy weight, getting kicked out of hockey after multiple offenses. Jack is the youngest and a "first class fuck-up, third class rock star".
