Storylines
Dr. Lisa Obrecht first appears at a hospital in Lucerne, Switzerland. Luke Spencer goes to the hospital looking for Anna Devane, who has gone there in search for her presumed dead daughter, Robin. Lisa approaches Luke, who's dressed as "Dr. Riet Von Schimmerman," and Luke show her a picture of Anna and asks if she's there. Lisa confirms she is and takes Luke to see her. Later, Lisa figures out that Luke isn't really a doctor and he tells her that they're really looking for Robin. Anna has found a girl that looks like Robin from behind, but isn't her. Lisa tells her that that girl had been transferred from Ferncliff, and Anna believes that Robin is dead after all. After Luke and Anna leave, Dr. Obrecht talks to an unseen man, saying that she's sorry he had to see Anna struggle since he cares for her so much. She also tells him that it's good that he moved Robin before Anna could find her. The man is then shown, and looks exactly like Duke Lavery, who has been presumed dead for over twenty years.

Later, it is revealed that the man appearing to be Duke is actually Cesar Faison in disguise, and that he also is keeping the real Duke hostage at the same clinic in Switzerland. In November, Lisa calls Faison and tells him that Robin has become more resourceful and he needs to come and take care of her. Robin knocks Lisa out, steals her phone, and calls home. When Lisa comes to, she gets the phone from Robin and has her restrained. Lisa listen to the phone and hears Robin's husband Patrick Drake on the other end, who doesn't believe that Robin is actually on the phone like his daughter Emma said. Faison goes to Switzerland and reprimands Lisa for letting Robin get to a phone and call home.

In December, Lisa is at Faison's apartment in Port Charles when Robert Scorpio breaks in to search for evidence that Duke is actually Faison. Lisa is able to hide and then escape before Robert sees her.

She learns that Cesar Faison has been captured with the real Duke Lavery being rescued. Robert Scorpio is stabbed with a lethal dose of a drug, but no official mentioning of if it was indeed fatal. She then takes Robin Drake to Jerry Jacks.
