Jessica was a minor character that appeared once in the Season 2 episode "Traffic Jam". She was Malcolm's friend 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 not to take the enjoyment out of 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 her phone number to Malcolm, a dog took the paper and ran off with it, leaving them out of touch forever.
