Jamie-Lynn Sigler opened up about getting emotional filming her guest stint on Grey's Anatomy amid her battle with multiple sclerosis. "Prior to this [opportunity], I was always trying to say, 'We can work around [my MS]. Don't worry, there's things that we can do to hide it.' [Jobs] always did and I appreciated it. I was met with such compassion and love. But now I had an opportunity to play somebody with MS," Sigler, 44, exclusively told Us Weekly. Sigler, who plays Dr. Laura Kaplan in the Thursday, January 15, episode of the hit ABC series, was grateful her character mentioned MS on screen.
