Passage: Jason is sitting on a bench in New York City waiting for someone to arrive. A voiceover explains that he has been waiting for a long time, but to explain why, he needs to go back to the beginning. Jason begins by telling the audience that every relationship reaches the "So..." moment, where someone in the relationship will want to take the relationship to a more serious place. At that point, Jason knows the relationship is over, as he is not ready to start dating.
Jason is currently working with his best friend Daniel at a publishing house designing book covers. Their friend Mikey, a young doctor who has been married to Vera since the end of college, comes to them after Vera requests a divorce. The three decide to go out to a bar and celebrate being single. The group meets up with Daniel's female wingman, Chelsea, as they try to get Mikey's mind off of his wife. Mikey meets a girl with glasses, while Jason meets Ellie, and hits it off with her after teasing another man that was trying to buy her a drink. Mikey gets the girl's number, but decides not to call, resolving to work it out with his wife. Jason sleeps with Ellie, but escapes her apartment when he discovers circumstantial evidence that she may be a prostitute.
Question: What are the first names of the three people that go to a bar to celebrate being single?
Jason.
