Jamie and Eddie's wedding day arrives, but Eddie is at odds with Erin grilling her over conflicting witness accounts and takes Jamie's attempt to ease the situation the wrong way, feeling further insulted. Anthony and Eddie later find that the witness lied under oath and Erin. Danny and Baez investigate the murder of a young man whose still obsessed ex-girlfriend, the prime suspect, swears that she had nothing to do with the man's death, as surveillance footage from another building's camera shows it was another ex. Garrett and Gormley are offended when Baker privately presents a plan to Frank, and a heated argument forces Frank to have them switch jobs for a day while agreeing on Baker's plan. All three struggle, and they make up the following morning. Frank also stresses over delivering the toast for Jamie and Eddie's rehearsal dinner; the entire Reagan family, Lena Janko , Rachel, Baez and Anthony are in attendance, with Archbishop Kearns officiating. Frank walks Eddie down the aisle at her request.
