Dr. Bill Hoffman encourages his group to 'get involved', in Dave's case to try and get serious with his latest girl-friend, only to learn that's his own daughter Sasha won't be told off by dad. Told he can't be Bill's in-law and patient, Dave resigns from therapy. Bill changes tactics to reverse psychology (but explicitly denying this), which Dave believes but gets Sasha furious with both of them - mission accomplished. Alas Dave doesn't take that lying down, except in a literal sense. Involvement doesn't work better for the other patients, except accidentally with Inger's ever-bickering noisy neighbors.
