Kate Beckett:  So , Lee wants fifteen to twenty - five with parole in _ ten _ for giving us Tyson 's new alias , and I need to give the ADA a recommendation . This might be our chance to get 3XK , Castle .
Richard Castle: No . It 's a setup . Jerry Tyson gave that gun to Philip Lee knowing he would use it , so there 's a good chance he knew we 'd eventually get to Philip .
Kate Beckett: Maybe . So what ?
Richard Castle: So nothing Tyson told Philip would be the truth . Giving Philip Lee a good deal for bad information , that 's just another win for Jerry Tyson .
Kate Beckett: Are you sure ?
Richard Castle: Sure enough . Jane Herzfeld deserves justice . Life in prison for Philip Lee . No deals . We 'll get 3XK . And we 'll do it right .
Kate Beckett: Damn , Castle . Look at you thinking like a real cop .
