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.
