Giovanni and his clients (spoilers)

We meet Giovanni's clients in ways that are humorous and thought provoking in terms of relationships. But we don't have a measure of Giovanni as a therapist until he tells them he is closing his practise and when Oscar says his goodbye. Poor Oscar. I found these endings as poignant as Andreas's death.

Ever tried, ever failed?
No matter.
Try again, fail again.
Fail better.
