What happens in Vegas, stays in Vegas. Or at least 90210's Adrianna hopes it does.

Fall Preview: Get scoop on your favorite returning shows

When the CW series ended last season, Adrianna (Jessica Lowndes) boarded a plane for Sin City after her ex-lover Dixon (Tristan Wilds) didn't show up to rekindle their relationship. Little did she know that Dixon was actually en route when his car was side-swiped by a massive truck. How will she handle the guilt when she meets a new man and then learns about Dixon's crash? Executive producers Patti Carr and Lara Olsen spoke to TVGuide.com about Dixon's fate, the return of Lori Loughlin, the show's milestone 100th episode and more.

The season left off with Dixon getting side-swiped by a truck. How will that be resolved when the show returns?
Patti Carr:
We won't give away the outcome of Dixon's car crash, but it has a ripple effect and blows up everyone's lives in different ways.

Lori Loughlin, who plays Dixon's mom, comes back, which can't be a great sign.
It's really a very emotional and touching moment when she returns. [It's] one of my favorite moments in the premiere.

Will she be around for more than one episode?
Lara Olsen:
Currently she's only in the premiere.

Exclusive: Ne-Yo to make guest appearance on 90210

When we last saw Adrianna, she thought Dixon was a no-show. How does she react to the truth?
Adrianna was getting on a plane to Vegas with Austin to perform. ... The episode comes back about 15 minutes after we left, and you see how [everyone] finds out. They don't all find out right away. Their actions before they know and after shape their lives for the rest of the season.

Are you saying something happens between Adrianna and her new love interest Taylor (Wes Brown) before she hears about Dixon?
Carr: Some things happen, as they do in Vegas.

What about Max (Josh Zuckerman) and Naomi (AnnaLynne McCord)? Last we saw them they were running off into the sunset.
They make a big decision about how they want to proceed with their future, and it also sparks more things than they expect. They make a pretty bold choice, and it's something we follow the whole season. We also get to meet Max's best friend and business partner played by Trai Byers.

Denise Richards lands at 90210 as "mean girl" for 100th episode

Can Annie (Shenae Grimes) please be single this season? Girl needs a break from men!
The arc for her this season is trying to figure out what she does want and then how to go after that.

Carr: She's coming into this season with the intention of focusing on herself and who she is, but she does wind up meeting somebody who's an interesting love interest [Riley Smith]. He appears in the second episode and Annie first starts conflicting with him. She has had some pretty bad luck, but this is something to look forward to for her.

Will Teddy (Trevor Donovan) be around more now that he and Silver (Jessica Stroup) are having a baby?
We see Teddy on a recurring basis, but it's a major storyline and one of the biggest we wanted to wrap the whole season around. It'll go through the end of the season.

Carr: In terms of them having a baby, once you decide to do it, there are usually not a lot of complications that arise. [But] there are with them.

This season marks the 100th episode. What do you have planned besides cameos from Carmen Electra and Denise Richards?
I don't know that there's anything else we could fit into the 100th episode. They're going back to their high school homecoming as alumni so they're running into a lot of characters from the past. But it's not a "put your life on pause" episode. Everything continues to move forward in a pretty dramatic way against a backdrop of probably the biggest episode we've done production-wise. Going back to their high school reunion also brings back a lot of old things to the present and also causes everyone to examine who they are and reveal things about themselves in different ways.

90210 premieres on Monday, Oct. 8 at 8/7c on The CW.
