Jessica was a minor character that appeared one time in the episode "Traffic Jam". She was Malcolm's girlfriend when they met up with each other in a huge traffic jam. Jessica liked Malcolm and was one of the few people who could tolerate his egotism and endless complaining. She gave him the advice to not take enjoyment out of the terrible things in life in order to be a happier being. The two of them had to break up however, because they lived very far away and when Jessica tried to give Malcolm her phone number, a dog took the paper and ran off with it, leaving them out of touch forever.
