He is caught, but the couple remains penniless. Jennifer then learns she is pregnant, but Jack's joy is not great. He thinks he is suffering a relapse of Hodgkin's disease. Though he is not ill, Jennifer goes to New York to do a TV show with Calliope. Jennifer gives birth later that year to a daughter, Abigail Johanna. The following year, Abigail is diagnosed with Aplastic Anemia. Jennifer teams up with Austin Reed to find the environmental cause of Abigail's illness. It is soon revealed that Jack was the one who had allowed the toxic waste dumping and was responsible for Abigail's illness. Overwhelmed with guilt, Jack leaves Salem and Jennifer behind. Jennifer begins dating Peter Blake after Jack is gone. Peter is involved with drug trafficking at the time. Jennifer's mother Laura sees Peter with a lowlife by the name of Leo as the two of them scheme to make it appear as if Laura is having a mental relapse. Jack returns to Salem and spies on his ex-wife and her current love. Jennifer begins to try to find a man named Clark, who her mom had feelings for. It turns out that Clark is actually Jack. Jennifer is devastated and goes through with her marriage to Peter. Jack tries continuously to prove that Peter is devious but to no avail. A year later, Jennifer and Peter separate when she finds out he lied to her. Jack catches Peter with a syringe meant for Jennifer so that Peter can drug her and then take her and Abigail out of the country. Jack ends up shooting Peter, and it looks like Peter has died. (Stefano switches Peter's alive body with the dead body of an old associate wearing a Peter mask.) Jack is sentenced to serving life in prison for the death of Peter, and Jennifer vows her eternal love for Jack every day. Jack breaks out of jail and takes Jen with him to evade police. They all are on the run for a while, until they join up with a circus. Jack becomes a laborer and Jen the assistant with Abby, their daughter. Abby strikes up a good friendship with the ringmaster's son. Eventually, Jack and Jennifer flee for Africa. While in Africa, Jennifer and Jack experience some problems with their relationship, especially when Jennifer falls for a young man named Colin Murphy...whom she does not realize is Shawn Brady's nephew! She flees to Ireland with Abby, where she ends up getting herself in trouble, and then has to come back to Salem with Bo.
