will guest-star in three episodes of the new ABC comedy series, In Case of Emergency
. Her first episode airs Wednesday, Feb. 14 (9:30-10:00 p.m., ET/PT). Seymour will play Jason's mother, Donna.
In her first episode, "Oh, Henry!," Jason, on the verge of going to jail, can cut a deal if he rats on his Uncle Henry, who happens to be Donna's favorite brother.

But the fireworks don't end there, as Donna asks Harry to give her a ride home alone.
