When Tony DiMera was murdered during the wedding reception and John Black the accused, Jack and Jennifer joined forces to prove his innocence. They went undercover at the Blue Moon, but just as they were about to prove Peter and Jude were linked, there was a police bust. Back in Aremid, Jude took Jennifer hostage, and Jack let him go to save Jennifer...who escaped on her own, complete with a matchbook containing the numbers to a bank account in the Cayman Islands. When the two went down there to check it out, Peter magically had the names on the account erased at the very moment they were accessing it. Then they learned that Bo Brady was looking for Hope Brady, who had disappeared, in Aremid, and joined the search. Jack watches Peter shoot Jude in cold blood, but everyone believes that Peter did it in self-defense.
