Obsessed.

In this week's Throwback Thursday poll, Soaps.com takes readers back to 1989 when "Days of our Lives'" Cal Winters became fixated on Kimberly Brady...

Nick Fallon isn't the only creepy, troubled ex-boyfriend to have walked the streets of Salem. Back then, Cal, who became Kim's lover when they thought Shane Donovan was dead, became obsessed with her after Shane returned home very much alive to claim his love. Cal even went so far as to kidnap Kim and take her to a cave in a mountain. Shane saved her, of course, and Cal was sent to prison.

Prison wasn't enough to stop Cal. His obsession continued from behind bars, and he acted out when he learned Kim was pregnant. Do you remember what Cal did after he found out this news? Vote in our "Days" poll:
