Recenetly he was almost killed in a bomb blast meant for him and it looks like he is in trouble, so he's gone into hiding with Ellen by his side.
In order to help protect Serena, Lucy married Rex Stanton. With the help of Eve, Kevin and Scott, they all managed to get the evidence they needed to send him to jail. From prison, Rex told Lucy that he had poisoned her tea and that she would die soon. At first she thought it was a bluff, but she started to get sick and soon was sent to General Hospital.
