Nick listens in as Mitch/Matt is talking with Sienna. When he sees that they’re alone, he runs in, spins Mitch around, and sucker punches him.

Sienna runs in between them and asks him why Nick hit Mitch.

Mitch asks who this guy is. He proclaims innocence.

Nick yells at him and calls him Matt. He says he’s obviously pretending and warns him to stay the hell away from his family. He stalks out of the bar, furious and seething.

Sienna looks at her husband in confusion. “What the hell was that all about?!”

Matt says some thug just came into the bar and beat him for no reason at all! He doesn’t know why the man would call him Matt Clark.

Sienna tells him that was Nick Newman, Noah’s father. Why does he believe that Mitch is someone other than her husband?

Matt doesn’t know. Nick obviously belongs in an institution! What does she want him to say?

Sienna thinks this doesn’t pass the sniff test… Nick Newman is rich and powerful; he doesn’t seem to be the type to punch someone for no reason!

Matt says she should be thankful that he didn’t let loose on the great Nick Newman. He warns her that if she doesn’t drop it, he’ll be tempted to do just that!

Later, Sienna and Mitch are discussing alcohol orders for the bar, but Sienna won’t let the fact that Nick came in and punched Mitch. She asks if he knew the Newmans before he met her.

Matt takes her arm and tells her that she should tell him the truth about her and Noah Newman… He’d like to hear that story!

Sienna brushes it off and says there’s no connection between her and Noah Newman, no matter what the detective thinks. She became friendly with Noah because Mitch wanted her to answer all his questions. She was following his lead on a business venture… Unless it wasn’t just a business venture. She asks him again why Nick Newman insists that he knows Mitch as Matt. What isn’t he telling her?!
