Season 9: Episode 20 - Grandma's Pie

Grandma's Pie: Zoey is coming home from London and Walden dreads telling her that he’s in a new business venture with Billy and his ex-wife, Bridget. It clearly doesn’t go over well with Zoey so Walden then asks her to move in. If Zoey decides to move in, Alan has to move out. Evelyn and Lindsey’s mother hit it off so well that they are moving in together (Evelyn is now a lesbian).
