While Dallas prepares to return to TNT for its third season, juicy story lines including someone getting pregnant, a shooting and another death, were revealed.

The show's Executive Producer Cynthia Cidre told TV Guide, "We open with Bobby (Patrick Duffy) at the Ewing cemetery looking at the graves of J.R., Miss Ellie and Jock, saying, 'I guess I'm the only one left now. I hope not to disappoint you.'"

Aside from aiming to make them proud, Bobby's marriage to Ann (played by Brenda Strong) is going to be on the rocks and he could end up cheating with Jenna Wade (Priscilla Presley) or a new woman.

Sue Ellen's (Linda Gray) drinking issues will resurface after she finds out John Ross (Josh Henderson) has been cheating on her, leading her to have flashbacks of J.R. doing the same. Cidre said that Gray initially had an issue with this story line but is now "into it."

Fans will also have a face to the Mexican compound dweller, Joaquin, who was mentioned lat season. Executive Producer Michael M. Robin said, "He will be helping Elena on her revenge path."

Robin also revealed that Christopher (Jesse Metcalfe) will meet a new woman, Heather, played by AnnaLynn McCord (Naomi Clarke of CW hit series 90210) who he'll have a fling with this season.

"Christopher stumbles upon Heather in a fight with another ranch hand, which turns out to be her ex-husband."
