Bobby is working at Ewing Oil for reals now. We know, because he's building an office in sweet late 70s style - with all the brown decor that entails. Since he's a Big Boy now (he's even wearing a suit with elbow patches!) he thinks he should be in on all the dirty Ewing Oil secrets. Against JR's wishes and better judgment, Bobby takes home The Red File™. Shocker of shockers: The Ewings have been paying off a crooked politician for years! No way! Also, did we mention that the crooked politician's is named "Wild Bill"? The only proof is a document in... The Red File™, which Bobby promptly loses behind the couch when Pam suggests they get it on. *sigh*

Meanwhile, Sue Ellen is horny as faq because JR is too busy checking out his secretary Julie's "red file"... Julie, who has been with JR for far too long, realizes that she wants something real and not be just JR's side piece anymore. She tries to relay these feels to him. He laughs it off and pays her $100 like she's a sex worker. Dude, you did NOT. Julie is now piiiiissed! She decides to seek revenge by slipping a little Red File™ action to Cliff Barnes (both literally and figuratively). Cliff immediately throws Wild Bill and the Ewings to the wolves. Everyone assumes it was Pam that gave Cliff the Red File™ (ew!), because... duh. Pam figures out what really happened, because she's the only really smart one in this first season. She confronts Julie and is all, "GURRRRL, I am NOT going down for this!" Julie realizes it would totally be a really crappy thing to do to Pam, so she faces the music by walking tits up into the office and throws down her resignation. 

JR: Why?

Julie: Because you have to ask that question. 

Eff yeah, Julie. Eff yeah.
