Zoe, a nurse, relied on her mother-in-law, Denise, to babysit her son, Leo. But when Leo became visibly distressed around his grandmother, Zoe grew concerned. Eventually, Leo revealed that Denise had been trying to swab his mouth with a cotton bud, scaring him.
Confronting Denise, Zoe discovered she had been attempting a secret DNA test, suspecting Leo wasn’t Andrew’s son due to his blonde hair. Furious, Zoe demanded that if she and Leo took a test, Andrew should as well—to confirm his own paternity. Shockingly, the results revealed Leo was indeed Andrew’s son, but Andrew’s biological father was not the man he had always believed.Denise’s long-hidden affair had fueled her paranoia, ultimately fracturing her relationship with Andrew. He and Zoe chose to distance themselves from her, focusing on their son and moving forward as a family.
