This week on "The Real Housewives of Orange County," the ladies let their hair down in Tahiti as they swam with sharks, indulged in some cocktails, and drove golf carts into restaurants. So what's in store for them next week? 

Last week, Vicki Gunvalson started the drama when she began talking about how women who didn't work should ask their husbands permission to spend their money. Meghan Edmonds thought she was being called out and said that maybe Vicki was jealous of her lifestyle. The episode ended with Vicki wondering what Meghan would do for a living if ever her husband decided to leave her for another woman. 

This week, there was more drama between Vicki and Meghan as talk turned to motherhood. Meghan tried to join in with her stories about being a stepmom, but she was immediately shut down by the other ladies. 

"It's not the same when the children aren't your own," Vicki said when Meghan mentioned her love for her stepchildren.

Eventually, all the put-downs got to Meghan and she cried over her lack of biological children. 

In her Bravo blog, Meghan said that the Housewives might have misunderstood her when she said that she wished she were her step kids' real mom. She explained that she never wished that their mothers didn't exist and she knows that she can never replace them. 

"I was simply trying to stress how much I love my step kids," Meghan wrote, adding that sometimes it can be hard not to be able to make decisions for them since she feels so strongly involved in their lives. 

This week, the ladies also learned that Heather Dubrow was close friends with Jim Edmonds' previous wife, Alison, and Shannon Beador took offense at this. 

"It's against Girl Code to be friends with the third wife when you're friends with the second wife!" Shannon exclaimed. "It's just not cool!" 

Next week, it's going to be all about Girl Code as the women continue their stay in Tahiti. 

After a night of drinking, Vicki and Shannon discuss the details of David's affair, as it's something that still hurts Shannon deeply. Meanwhile, the other ladies head out to an excursion that puts them in deep water. Tamra Judge, wanting to get everything out in the open, starts a debate over girl code, and Meghan surprises the other Housewives at the final dinner.

"The Real Housewives of Orange County" airs every Monday at 9 p.m. on Bravo.
