Rogelio and Darci meet when Rogelio seeks her out to find a match in her dating service. He goes on dates and very intensely rejects women because he's really looking for something to father a child with. Once Darci realizes this, she suggests that the two enter into a non-romantic co-parenting agreement. Rogelio agrees, but quickly develops feelings for Darci and while she is apprehensive at first, being very cynical about relationships, she eventually admits to liking him too and to be scared of letting someone in truly. They decide to take having a baby slowly, now that they're involved. Rogelio eventually agrees to star in a reality show for Darci's sake, starring her and Rogelio entitled The De La Vega-Factor Factor.
Three years later, Darci and Rogelio have broken up because Rogelio couldn't go through with having kids with Darci after all. She resents him for having broken their deal (perhaps her heart?), but they still work together as Rogelio is contracted to the reality series until he breaks his contract. About 6 months later, the day before Xiomara and Rogelio's wedding, Darci shows up in Jane's car, pregnant with Rogelio's child. Although Xiomara initially calls off the wedding, she decides timing will never be perfect and they marry, while trying to mend fences with Darci so she and Rogelio can successfully become a family with Xiomara as well.
