Pat Sr.: Let me tell you, I know you don't want to listen to your father, I didn't listen to mine, and I am telling you you gotta pay attention this time. When life reaches out with a woman like this it's a sin if you don't reach back, I'm telling you its a sin if you don't reach back! It'll haunt you the rest of your days like a curse. You're facing a big challenge in your life right now at this very moment, right here. That girl loves you she really really loves you. I don't know if Nicky ever did, but she sure as shit doesn't right now. So don't fuck this up.
Trivia: When Tiffany and Pat get into the fight in the diner and then stop in front of the movie theater, take a look at the marquee. The movie playing is 2008's "The Midnight Meat Train", which actually stars Bradley Cooper.





Answer: It's not exactly common, but yes, it would be up to the judge, and establishing that a person is a "clear and present danger to themselves or others" can result in involuntary commitment in Pennsylvania, where the film takes place. In this case, it would not be hard to argue that, "the person has inflicted or attempted to inflict serious bodily harm on another and that there is a reasonable probability that such conduct will be repeated" (50 PA. CONS. STAT. ANN. ยง 7301 (b) (1)), as he had just physically assaulted his wife's lover and she'd obtained a restraining order. His mental health problems would have been well-documented, so it would have been easy for a judge to order him to undergo psychiatric evaluation, which could (and, in the film, does) lead to extended involuntary commitment at the discretion of a mental health professional.
