Stavros Cassadine (then John Martinuzzi) was obsessed with Laura and wanted her to give him a child.
When Laura finally escaped, she left baby Nikolas behind.
Nikolas was played by Tyler Christopher back then, who would continue to play the character until 2016.

Christopher opened up on"State of Mind"about howhis life had reached rock bottom.
He recently discussed what playing Nikolas really meant to him, too.
To be on that show, I had to be raw and vulnerable."

The actor even confirmed he’d be happy to return to the show someday.
“It ended up being great,” he enthused.
Christopher replied, “I can’t go away from Nikolas.
I have to say that.
I created that character.”
And, frankly, so are we!
