 While Rex is the eager beaver in his bio-ethics class,  professor Putnam  (Rolf) explains why he replaces Dr. Guerrero: to study the twins, which are utterly human, and he warns the others they must be supportive, not small-minded like Cynthia. John prepares Marlena to bring his spy-gear into the DiMera mansion, but Colin brings Tony a truth serum to use on her while she  waits  for the twins who won t come because of the Halloween party. Brady has another go at Philip as he observes Chloe who enjoys following his mystery trail, a series of gifts and memories, but when it ends at the dock... Shawn is still distracted by the kidnapping; Belle has a feeling to know Putnam, but he convinces her the twins won t be hurt while he interviews them, willingly; Rex quickly notices he s not from Boston and his MIT diploma is false, but when he suddenly slips the green bracelets on their wrists they become utterly docile and he tells them they must be tough to accomplish Stephano s mission. Marlena manages to make photographs in Tony s office; before he really gets her talking, John bursts in after her earring/transmitter fell in her glass of water.
