Lynette Scavo had a bigger story in episode 2.22, that showed her freaking out inside the plane, while flying back to Fairview after seeing Tom with Nora. She basically tried to call her husband, but phone calls are forbidden inside planes, so she was ultimately detained, and a flight attendant told her that if it seemed like Tom was cheating, he probably was. This is all a part of the extra features on the season 2 DVD, and is available on YouTube. Apparently, there's also an unaired storyline there regarding Susan's adult novel, about her life, but I never saw it.

Rumor also has it that Ethel Hollings, the name of the patient George typed into his system in 2.08 after discrediting his ex-fiancée, Leila, was also supposed to have a 3-episode arc, but I have no idea where that even comes from.
