WHEN WILL WE SEE 'NUKE' NOAH AND LUKE OF AS THE WORLD TURNS IN SOUTH AFRICA?

Nuke started in the Summer, around the time of Jade's shenanigans so I think you're close. Is Maddie in town yet? I only watched ATWT occasionally, so I can't be sure of the details, but it sound like they're playing Spring 2007. According to IMDB, Noah's first episode is #13,028 -- June.
