Longtime "Days of Our Lives" viewers may remember that Jeremy Horton is the son of Dr. Mike Horton and Robin Jacobs. The character was born in the late 1980s and had a dramatic start to life. Jeremy's parents met in 1986 when they were both working at Salem University Hospital, however, their religious beliefs drove a wedge in their romance. Although they had very strong feelings for one another, neither was willing to convert to the other's religion. Eventually, Robin and Mike called it quits and she went on to marry Mitch Kaufman. However, she soon found out that she was pregnant and didn't know who the father of her child was. Although Mike and Robin did give their relationship a second chance later on, they were unable to make things work between them.

Robin ultimately left Salem, but when she returned in 1988 she brought her son, Jeremy, with her. It was then that Robin admitted to Mike that he was Jeremy's biological father. Mike's relationship with Jeremy became a priority and had an impact on his romance with April Ramirez. When Robin and Jeremy left Salem again and moved to Israel, it wasn't long before Mike followed. Fans didn't see Jeremy again until 2007 when he came home to Salem and began to cause trouble.
