On last night's The Ultimate Catch, Ericka snitches to Chad that Rubi's true colors have come out: she is "always singing." So, obviously, the only logical explanation is that Rubi is solely on the show to boost her career.
Seeing as Chad thinks Ericka has fallen into Tara's shadow, which distracts from their own relationship, Chad muses, "Who the hell is here for me?"

Chad later got rid of Ericka, along with Jasmine.
