It's a great place to drop your inhibitions, Jim, you know; grow a beard, swim naked
—Life of Iris
Necessity Is a Mother is the 10th episode of Season 2 on FOX teen soap Beverly Hills, 90210.


Dylan cannot stand the fact that his quirky mother, Iris McKay, has moved in with him. He begins drinking, skipping school, and spending all of his time at a pool hall. Brenda resents Iris for abandoning Dylan as a child and for trying to step in and control his every move. Cindy, however, forms a bond with Iris and joins her for a number of new-age experiences. Brandon tries to watch over Dylan, who loses a lot of money in a pool game and is beaten when he can't pay off the debt. Although she wants to be a part of her son's life, Iris realizes that her presence is only hurting Dylan. She decides to return to Hawaii, and sets up a trust fund for Dylan with money Jack had once paid her to stay away. Brandon takes Dylan to an AA meeting. After Donna displays a knack for picking stocks in an economics assignment, Steve talks her into investing in the market with him.
