Tonight's penultimate installment of Devious Maids Season 2 set Marisol on a quest to find out the truth about Nick's past.

All season long this has been the core mystery. Aside from Nick's complicated past, a whole lot happened that now leaves us anticipating the season (and hopefully not series) finale.

So, what down on Devious Maids Season 2 Episode 12? Let's discuss...

Nick continued to refuse to share his past. Unfortunately for him, Marisol wanted the truth and wouldn't stop at anything to find it. Dressed as Opal and on a mission, she went through Opal's safety deposit box to find two things that were not all that shocking for readers who have thought for awhile now that Nick killed the Powells' son.

What did she find? Marisol found a bloody garment and an article titled, "Tragedy in Beverly Hills, seven year old found dead after hit and run." I expect that Marisol will have to go to the police but am wondering how the Powells will take the news. Most importantly, can Marisol forgive her husband? 

Meanwhile, Zoila struggled with her feelings for Javier and Pablo when she woke up with the latter. I'm hoping that she comes clean about what happened with Pablo before her trip to Paris and that Javier finds some way to forgive her. 

With Spence in rehab and Peri possibly reconsidering custody, Carmen was in for a surprise when Tucker showed up at Spence's door. Of course she wanted to help Spence out. Unfortunately, Carmen clearly wasn't meant to be a mommy just yet. It was so funny watching her try to take care of "Diablo" though. I honestly laughed the entire time as she tried her best. 

Elsewhere, I was so glad that Rosie recruited Lucinda and Didi's help to rescue Kenneth. She definitely needed more girl power to bring down Reggie, quite possibly the biggest snake ever. However, I absolutely hated that Reggie threatened Rosie about sending her back to Mexico.

She's got to take care of him once and for all. She needs Spence and her gal pals to come up with a plan to teach him a lesson and also to keep her and Miguel safe. 

As for Valentina, she revealed to Ty that she told the police everything she knew about Ethan. Ty and the other boys think that killing Valentina is the only way to truly silence her. I seriously can't stand Ty and hope that Valentina doesn't get hurt. 

Other Thoughts:

• I loved the scene when Genevieve asked Adrian for help to get tested to see if he could possibly be a donor. Adrian seriously always makes me laugh.  
• It was nice to see Carmen focusing on her career again. She's always been incredibly passionate about it, and I want to see more of this.
• Don't forget to check out the Devious Maid quotes section for some laughable moments.

Overall, "Proof" was about forgiveness and was a strong installment that finally revealed Nick's secret. We are officially a week away from the season finale and I can't wait to see how this season will close out.
