Disaster Episodes happened through Season 3 and 7. These episodes are when something very bad or life changing happens and put things into perspectives. Much of the disaster episodes revolve around almost all the main characters on Wisteria Lane. The episodes generally occur mid-season, which involves a death of a major or recurring/minor character. A theme that runs through each disaster episode is that someone causing grief to a character on Wisteria Lane are usually killed of in the occurring circumstances.
