(This isn't really a topic, I guess. I just wanted to write my thoughts about what happened after Justin left for New York.)
I have a lot of problems with the series finale. But the thing that gets me the most is what happened between Brian and Justin. Now I agree that they shouldn't get married (at least, at this time) because Brian wouldn't be entirely happy and Justin hasn't entirely discovered himself yet. But Brian also isn't entirely happy without Justin. In fact, I'd say he's more happy with Justin, in any way he can get him, than without him. Yet it seems that the writers don't agree with me, but screw them. I'll make up my own ending. Since I hated the series finale and the way the writers decided to end things between Brian and Justin, I am writing what I think happened after Justin left for New York:
After several years of painting in New York, Justin finally receives the fame and acclaim he deserves. He's doing incredibly well, and is happy that he's finally able to support himself.
Meanwhile, Brian's business in Pittsburgh is booming, and he decides to expand (under the counsel of Ted). Where to expand? New York, of course. Despite his outward calm and cool appearance, Brian never got over Justin, and let's face it, he never will. He's his soulmate for crap's sake.
Justin, meanwhile, has maintained the same feelings for Brian that he's always had. From the first moment he saw Brian outside Babylon, he knew.
Since I'm not a writer, I'll just cut to the ending. Brian goes to New York to set up Kinnetik. At this point, he's still deciding whether he'll relocate to New York with the business, or stay in Pittsburgh. In New York, he reunites with Justin (and it's freaking hot, by the way). In the few months it takes to set up the business, Brian and Justin fall in love with each other more strongly than ever. They even frequent the gay clubs together in typical Brian fashion. Justin, being a successful artist, and having made an obscene amount of money, decides he wants to move back to Pittsburgh where he can work on his art. Because, despite the glamour of New York, it's not his home and it's not where his friends are. Brian, in turn, decides to return to Pittburgh for the same reasons (surprise surprise!), in addition to the fact that he never wants to lose Justin again.
Arrive Pittsburgh! And get this, Brian and Justin decide to get married (and it actually happens this time!). But it's a marriage with a twist. Since neither Justin nor Brian want to be without one another, both are willing to reach a compromise where their marriage is concerned. They can have extra-marital relations, as long as they had them together. Justin finally realized that, after being in New York, Brian is the one he wants even in spite of their differences. And he rather enjoys spicing their sex life up, as long as he and Brian do it together. And Brian is more than willing! They have two homes now: the loft and the country house in West Virginia, to satisfy all their needs. Don't forget about Babylon. It's been revived, and Brian, Justin, Michael, Ben, Emmett, Ted, the football star and the tweaked-out twinkie all dance to the thumpa thumpa together.
The point is, Brian and Justin end up together. Which is how it should be.
