Isabel Gillies portrayed Kathy Stabler from her introduction in the first episode of "Law & Order: SVU" until the character's tragic death in "Law & Order: Organized Crime." Her death prompted Elliot to come out of retirement and start working for the Organized Crime Task Force, an unfortunate turn of events that lays the groundwork for the spin-off. Even though Kathy has only appeared in 32 episodes of "Law & Order: SVU," the character's death prompted a wave of negativity directed at Gillies. However, she didn't let the fandom drama get to her.

"While I love Mariska and Chris, if their characters were falling for each other or not wasn't my concern," Gillies said at the time (via People). "Once they buried me, I continued on my life as Isabel Gillies, mom, wife, mahjong player."

Besides a guest spot in a Season 1 episode of "Sex and the City," Gillies has appeared in movies like "Metropolitan," "Wishful thinking," "Chocolate for Breakfast," and "The Girl Under the Waves." Gillies is also an accomplished author, having written two memoirs called "Happens Every Day" and "A Year and Six Seconds," as well as a novel titled "Starry Night" and a self-help book titled "Cozy: The Art of Arranging Yourself in the World."

As it turns out, Kathy Stabler isn't the only character Gillies has played in the franchise. She also portrayed a character named Monica Johnson in a 1998 episode of "Law & Order."
