Olivia starts having hallucinations that end up coming true. Eventually, Steve started to give her hallucinations more credit when they involve his mother. During the water poisoning scare in Port Charles, Steve received a call from Heather, saying she was worried about him, but Steve coldly rejected her. Afterwards, he finds out Heather escaped from Ferncliff. He's later approached by Jason Morgan, who tells him that Heather switched his wife, Sam's son with a stillborn infant. Steve is horrified by what his mother has done, and when Jason says he doesn't know where the other baby came from, Steve reveals he treated Téa Delgado and her newborn son the same night Sam gave birth. Jason eventually gets proof that Téa Delgado's "son" is Sam's baby, and tells Steve this. However, he also reveals that Heather has kidnapped the baby after posing as his nanny. After Jason leaves, Heather shows up, trying to make a new start with Steve and the baby, but Steve deceives her and tries to call the cops. Heather hits him over the head and escapes, and he's found by Olivia.
