Daniel Jonas took a liking to Chloe Lane (Nadia Bjorlin) even though she was to marry Lucas Horton (Bryan Dattilo). Chloe went through with the marriage but continued seeing Daniel on the side. Jealous of their relationship, Kate Roberts poisoned Chloe and framed Daniel, but her plan backfired. Daniel saved Chloe's life, and she divorced Lucas. Daniel and Kate then got engaged, but things did not go as planned.

Daniel found out that he had a child with Carly Manning (Crystal Chappell) and tried to build a relationship with his daughter. Assuming that Daniel was cheating on her with Carly, Chloe cheated on Daniel with Philip Kiriakis (Jay Kenneth Johnson) and got pregnant. She originally thought the baby was Philip's, and she left Daniel to marry him instead. Later, it was revealed that the paternity results were switched, and Philip was the biological father. However, years later, Chloe claimed that the child was, in fact, Daniel's.

For his part, Daniel went on to start a relationship with Jennifer Horton (Melissa Reeves), but his connection to Carly caused problems for the two of them. Eventually, Jennifer reunited with her ex Jack Deveraux (Matthew Ashford), leaving Daniel single again.
