Finally more news about Mary-Kate’s role on ‘Samantha Who?’ which is scheduled to air on Monday 10th November at 9.30pm EST on NBC:

Mary-Kate Olsen is coming back to primetime with a guest spot on Christina Applegate’s “Samantha Who,” and the actress will get in touch with her dark side in the name of comedy. In the episode, Mary-Kate plays a troubled young woman that Samantha meets while doing community service following an arrest, Access Hollywood has learned.

Sam makes it her mission to help Mary-Kate’s character, which ABC describes as a “bad seed,” regardless of her friend’s multiple warnings otherwise.
