Has Brothers & Sisters' Sarah found herself a potential husband in Gilles Marini?
The Dancing with the Stars alum begins his five-episode arc on the ABC drama Sunday as Sarah's French suitor, Luc Laurent, who "could be it for her," Marini tells TVGuide.com.
"It's more than a fling. He's different than her past [significant others]. It's a beautiful relationship between them," he says. "Going into the filming of the fifth episode, there was a lot of talk of me coming back, so you may not see the last of Luc."
But we — and Rachel Griffiths' Sarah — have to meet him first, which she does while in France and it was "love at first sight." "He thinks she's very charming, intelligent, driven — something that's missing from his relationships," Marini says. "That's why he makes a dramatic move."
