S06E03 — Happily Ever After

Harper can't let go of his obsession with Viveca Wells. He is convinced that she murdered her last husband, and when he learns she's engaged to be married again, he tries to warn her fiancé, Richard, who tells Harper that he knows all about her past, and he's okay with it. While researching the case with Ali and trying to fight his own attraction to Wells, he learns that Richard has been the man in her life all along. Nicco is upset because in the six weeks since he's been off of suspension, he hasn't worked a single case. Ali finally throws him a bone by having him interview a prospective witness in the case of a racially motivated murder and while Nicco gets the man to ID the suspect, he's not happy with it.
