This. 100% and then some. You will notice a pattern with good ole "Maurice". Season 1, Camille was being nasty to Kyle (ie: dinner party from you-know-where). Mauricio did not get involved in Kyle's issues with Camille because he was Kelsey and Camille's Real Estate agent, he did not want to lose them as Clients. I believe Camille even made remarks in one of her talking head interviews that Kyle needed to watch her step with her, as she had the power to fire Mauricio as their REA.
Next season, Mauricio is buddy-buddy with Ken and Lisa. He sold their house (the one that Pandora was married at), and found them their current house. Notice, now that the deal with the Vanderpumps is done, no more buddy-buddy. He argued with Ken in this last episode over what Brandi said.
This season, Paul and Adrienne haven't gotten divorced yet. What we are seeing is Mauricio sticking up for them over the Brandi situation. Guess who
was the selling agent for Paul and Adrienne's house???
Mauricio uses people to maintain his client base. He only wants to stay in the good graces of those for just as long as he needs them to make a commission.
Notice he doesn't defend the very cash-strapped Taylor or Brandi. They are of no use to him.
Mauricio's true colors came out last night. He is just as low as his wife.
