MARTHA WILSON

The last time that Martha was ever mentioned was in the first episode of the fourth season (The Chinese Girl). This was also the last time that George Wilson was mentioned by first name. It was never clear exactly what happened to them. In that episode, John Wilson explained briefly to the Mitchells that he signed the papers to buy George and Martha's house the previous week. The last time that Dennis mentions George is in Episode 110: You Go Your Way as "The other Mr. Wilson." The very last time that George was mentioned again was when John Wilson spoke to Dennis' Principal in Episode 115: The New Principal. John briefly mentioned George as "my brother." After that, George and Martha were just forgotten about.
