Wow... Jerry sure is a class A jerk! I hope Dorian tells Jade to never bring him along again. To read the signals wrong could happen once. Twice...? Then you're simply a douche.
As weird as it sounds, it seems to me the best thing that could happen would be for the delicate situation to reveal itself and make the news. Sure, it will make Dorian's life hell for a while, but as it is now? He's not living his life, he's barely existing. He's someone else and so very unhappy. Something needs to happen and soon.
