Desperate Housewives

The four that started it all are coming back together for the final season of Desperate Housewives. But instead of a Wisteria Lane block party, it's a dead body that will pull Susan, Lynette, Bree and Gaby into each other's lives in Season 8. "We're bonded together by this secret, and that really tests all of our friendships, but it also brings us closer together," Eva Longoria tells TVGuide.com. "Every episode is a roller coaster: one minute, we're mad at each other and then we're not mad at each other. One minute, we're together and we're the four musketeers, and then we're not."

This deep, dark secret is the fact that Carlos killed Gaby's abusive step-father in the season finale. Susan, Lynette and Bree walked in just in time to see the dead body and the five longtime neighbors agreed to cover-up Carlos' big oops. But how will this secret affect their love lives? Will Gaby and Carlos be able to handle the pressure? Will Bree be able to keep the murder hidden from her detective boyfriend? Is there still hope for Lynette and Tom? Check out our relationship roundup to see what's next for all the couples in Fairview:

Gaby and Carlos: The murder, and the subsequent cover-up, will hit Gaby and Carlos (Ricardo Antonio Chavira) hard, but Gaby will put her best foot — or should we say hip? — forward to help. "Carlos has a lot of guilt and so she's trying to pull him out of it," Longoria says. "That's when she takes pole-dancing classes, to try to put the spice back into things."

Desperate Housewives' executive producer and cast on the last season: All bets are off

Lynette and Tom: The homicide happened just when Desperate Housewives' most resilient couple, Lynette (Felicity Huffman) and Tom (Doug Savant), decided to split up. "Everything she's counted on, everything that she thought that she knew about her world is falling apart," Felicity Huffman says. "Not only is her family at risk because of divorce, but now her family is at risk because they're accessories to murder." And while Tom may be enjoying the single life (and finding a new lady friend), it doesn't appear that Lynette will be doing the same. "She's kind of in the pits. She's in that part of when you're single and you go, 'I'm old and fat and ugly.' So right now it's really sad and hard," Huffman says. "I don't know if she's going to maybe start to date."

Susan and Mike: There will be some marital discord ahead for Susan (Teri Hatcher) and Mike (James Denton) when Mike finds himself in the middle of the cover-up. "The women have this mystery going on with this body and everything, and Mike kind of gets pulled into it from a different source -- not the women," James Denton says. "So there's some tension there, because Susan's kind of gotten him back in trouble and he's got a shady past anyways. ... Obviously that gives them a little marital strife." But Denton doesn't see their problems turning into a more permanent separation now that viewers have already weathered one Susan and Mike divorce (and countless spats). "I think so much is invested in them being together — the first few years, that was so important to the viewers so I can't imagine them splitting up. I think everyone will end well for them, but I don't know. You never know with [creator] Marc Cherry."

Bree and Chuck: Out of all the women on the lane, Bree (Marcia Cross) may have the hardest time keeping things quiet now that she's settling down with a cop. However, Cross says keeping her relationship with Chuck (Jonathan Cake) intact won't exactly be at the top of her list of priorities now that she's involved in a cover-up. After years of tumultuous relationships, she has guarded hope for Bree and Chuck's future. "I think she's got a little more on her mind than staying with someone, but I don't know, we'll see," Cross says. "These things weave their way in and out."

Renee and the New Guy: Renee (Vanessa Williams) won't be clued into the big mystery on the lane — probably because she's preoccupied with her hot new neighbor, Ben (Charles Mesure). "Vanessa's character takes a bit of a shine to me and says, 'I'm going after that,' and she does," Mesure says. "We kind of play with some of those expectations about her character and there's a lot of comedy that comes out of that as we kind of flip those expectations over." Renee is a strong woman, but it sounds like she won't necessarily be wearing the pants in this (possible) new relationship."You'll see a side where she doesn't get what she wants all the time and that's not easy for her," Williams says. "She's used to calling the shots and being a big shot on the street and being a city slicker and knowing how to maneuver and out-think and out-wit everybody and it kind of comes to a screeching halt this season."

The final season of Desperate Housewives kicks off Sunday at 9/8c on ABC.
