It turns out that Laura conceived a child with Stavros Cassadine during her time in captivity, and that was baby Nikolas. Before telling Luke, Laura goes to see Stefan Cassadine (Stephen Nichols) to see if a test can be arranged for Nikolas, since he is the only person left who could possibly be a match for Lulu.
Luke is suspicious that something is going on, and finally, Laura has no choice but to tell her husband about her other son. Geary and Francis did their usual spectacular job together, and Luke is repulsed at the thought of Cassadine blood in his daughters veins and shocked by Laura's admission. His relationship with Nikolas is an uneasy one, though over time, it gets much better.
