When Annie realizes that Olivia's elated to have regained control of her drinking, she adds a second dose of the potion to Olivia's morning coffee. Just as Olivia congratulates herself on her new life, the potion takes effect. Maria wakes up and asks Tess where she is. Tess responds that it doesn't matter where she is, because she's never going to leave alive. When Maria asks where Ben is, Tess says that Ben won't be coming to Maria's rescue this time. Then she tells Maria that Benjy isn't Maria and Ben's son, he's Tess and Derek's. She said that Maria had been held captive by her and Derek for five years, but then she escaped. Luckily for them, as well as for Maria, Maria still had no memory of those five years, so she and Derek had been able to continue with their plans. Then Tess tells Maria that Tim had gotten in their way, so they had killed him. Then Tess drugs Maria. (thetvdb.com)
