She is Shawn's mother. Just like her husband, she is often away because she is busy with work. She feels really bad about not being there for her son and is trying to make up for it. She and Aunt Jessica don't always see eye to eye. She has a kind nature, a little unsure of herself at times, but also wants what is best for Shawn. 

(The actress for this character needs a google docs, so I can share the script!)
