08 Before Delphine could speak , one of Cillian's soldiers approached with a black briefcase . " Boss , this just arrived from the Brennan compound . Their messenger said it was urgent . " Cillian grabbed it with shaking hands . Inside were all the O'Sullivan gifts , the traditional tokens of alliance between families . And a simple note : The Brennan family returns these gifts with thanks . We wish the O'Sullivan family well in all future endeavors . - Vincent Brennan Not even Saoirse's name . Her father had written it , making it official family business . Cillian's legs nearly gave out . " She's really gone . She left me ." " Left you ? " Mrs. O'Sullivan snatched the note . Reading it , her face went white , then red with rage . " That little bitch ! Does she know what she's done ? This is a declaration - the Brennans are cutting ties ! " " Ma ! " Cillian's voice was ice . " Watch your tongue . " " Watch my tongue ? She's humiliated our entire family ! Every crew from here to New York will hear about this ! " The gathered guests - rival families , allies , neutral parties - whispered among themselves . In their world , a bride abandoning a groom meant something serious . Either the groom had betrayed her unforgivably , or war was coming . " I have to find her . " Cillian started for the door . His mother grabbed his arm with surprising strength . " You'll do no such thing . You have a wife and child to think about . Your brother's child ! " " I never wanted this ! " The words tore from his throat . " I love Saoirse ! " " Then you should have thought of that before taking vows ." Her voice turned cold . " You made your choice . Now live with it . Delphine is your wife . That child is your responsibility . Act like an O'Sullivan . " Around them , the guests watched the family drama unfold . In their world , showing such weakness was blood in the water . Cillian looked at Delphine in the wedding dress meant for another woman . She attempted a trembling smile . He turned and walked out , leaving her at the altar .
