In the beginning of 2010, Sonny shoots undercover cop Dominic Perelli, who turns out to be his son Dante Falconeri. Meanwhile, Elizabeth cheats on Lucky Spencer with his brother Nikolas Cassadine and becomes pregnant. The baby is Lucky's, but Helena Cassadine changes the paternity results to say that it is Nikolas's son. Also in early 2010, Kristina's is attacked by her boyfriend Kiefer Bauer, but lies and says it was Ethan Lovett. While driving Kristina to the hospital, Alexis hits Kiefer with her car, but is in a state of shock and keeps driving. Kiefer dies from his injuries. Sonny goes on trial for Claudia's murder, but Dante learns Michael (now being played by another recast Chad Duell) killed her and he is sent to prison. Jason voluntarily goes to prison to protect Michael. Eventually Michael is released from prison, and Jason soon after. Carly vows to get revenge against Dante, and tries to break up Dante and Lulu by hiring Brook Lynn Ashton to seduce him. Meanwhile, Franco returns and kidnaps Elizabeth's newborn son, Aiden, causing the hospital to be locked down. Kiefer's father tries to take revenge, shooting Mac and Ethan before attempting to shoot Kristina. Mac kills Warren. Lucky eventually finds the baby and returns him to Liz, and Franco escapes.
