Alexis explains how bad she felt last year in Costa Rica.

Vicki makes her decision carefully, and opts to stay...for now.

Gretchen explains that she didn't feel bullied when people questioned her and Jeff; people just brought different opinions to the table.

Tamra decides to head outside to check out how Alexis is doing.

Alexis reveals that she felt she needed to go on Xanax to cope.

Tamra tells Alexis to go cope at home.

When Tamra returns inside, Vicki ultimately decides to leave.

In the car, Vicki recounts all the times that Tamra has hurt others, and starts to feel less badly about leaving the party.

Meanwhile, the gym is blessed!

Briana and Vicki catch up on the joys and challenges of motherhood.

Vicki gives Briana a knowing hug -- Troy is sick, and Vicki knows just how that feels!

Gretchen is off to visit Slade and his son, and might not be back to the 'OC for a week or two.

Tamra's excited for her date night at a Mexican restaurant.

Eddie and Tamra talk wedding: when will it be? Whenever Eddie is feeling less stressed?

Briana's excited to show off Troy to her mom's side of the family.

Vicki is shocked to hear that her mother was arrested for road-rage.

Vicki's family will drink to that! (And to baby Troy, of course.)

Lydia comes over to check in on Alexis, post-gym dinner.

Lydia suggests that Alexis fight her battles one at a time, and to start with a reconciliation with Heather.

Alexis agrees, but is nervous about the idea of moving forward with these ladies.

Vicki's brother is nervous about Ryan and Briana's influence over Vicki.

But of course her family brings up Donn, making moving forward all the more complicated.

Ryan explains specifically why he dislikes Brooks. Apparently he's made a few off-color remarks and envoked the "bro code."

Vicki's brother is shocked.

Heather works on teaching Colette some new words.

She just screams back. As Heather says, she's lucky she's cute!

Vicki meets her son, Michael, for lunch -- since he won't let her know where he lives they meet at a second location.

Bill comes along as well, and is happy to catch up with his nephew.
