S6·E22 All This and Mary Too

Colin visits Kelly and announces that he has kicked his cocaine habit. Kelly maintains that they are bad for one another and breaks up with him. Kelly gets a roommate, a troubled teenage runaway named Tara. Valerie has the house to herself as Steve and Brandon leave for a ski weekend with Clare, Susan and David. She hooks up with Colin. Susan challenges Brandon to a ski race, and they leave the designated runs. Susan injures her ankle on a jump, and the duo must fight the elements while awaiting a rescue team. Depressed by his split with Valerie, David mopes around the lodge. Everyone keeps introducing him to blonde girls named Mary. Donna hears news of a medical breakthrough that could save Joe's career. She must convince Joe to pursue the treatment (he doesn't want to get his hopes up), and goad her father into using his connections to Joe's benefit.
