Zoe, a nurse, often relied on her mother-in-law, Denise, to babysit her son, Leo. But when Leo started acting strangely around her, Zoe began questioning Denise’s behavior. Leo eventually confided that Denise had been trying to put a cotton swab in his mouth, which terrified him. Zoe confronted Denise, discovering that she suspected Leo might not be Andrew’s biological child because of his blonde hair. Denise had even considered a DNA test without consulting Zoe. The confrontation strained Zoe’s relationship with Andrew, who later agreed to take a DNA test as well. The results confirmed Leo was Andrew’s son, but a shocking twist revealed that Andrew’s biological father wasn’t who he thought. Denise had had an affair, which Andrew learned about through the test. Despite the shock, Zoe and Andrew chose to focus on their family, moving forward without Denise.
