In 1990, Nikki blindsided Victor by marrying his sworn enemy, Jack (Peter Bergman). An accident caused her to miscarry and develop a dependency on painkillers and alcohol, landing her in rehab in 1991.
Nikki and daughter Victoria (then-Heather Tom) had muddled through the awkwardness of having a shared lover — Cole — by 1994, the year her son Nick (Joshua Morrow) returned home from boarding school.
