With Frankie, Season 4 is all about strengthening relationships. Over the course of Season 3, Frankie becomes close to a woman named Bianca (Tennille Read). Having gone through the journey of having a baby with ex-wife Giselle (Olunike Adeliyi), resulting in their daughter Rhoda, Frankie helps Bianca through the process of getting pregnant. Going into Season 4, Frankie and Bianca’s relationship is shifting to romance, as the two take care of Bianca’s new baby, Solomon, together.
When Bianca gets in contact with her sperm donor, she starts to trust him very quickly, while Frankie is wary of the man. In the end, it turns out Frankie is right to be suspicious, as the man tries to steal from Solomon’s college fund, but Frankie stops him. Growing even closer to Bianca during these events, Season 4 ends with Bianca asking Frankie to officially become Solomon’s second mother and co-parent, legally adopting the baby, and she agrees.
