Forgiven

S1, E38: Mr Sesemann comes to Dörfli with Grandmamma for a visit. When he sees them, Peter thinks they're after him for breaking the wheelchair and he decides to run away. At the cabin, everyone's happiness (as Mr Sesemann and Grandmamma have seen Clara walk) is short-lived when Brigitte arrives and tells them that Peter is gone. They all look for Peter and Heidi finds him in the treehouse.
