The burnt letter

Peter is entrusted with delivering a letter to Onji. Heidi distracts him showing the kid how Picchi has already learnt to fly and they leave to the high pastures where some goats get lost as the kids play. Peter and Heidi find the goats but a thick fog isolates them. Joseph, Ohi's dog, finds them and shows them the way back to the pastures where Onji waits. At the end of the day, he gets to read the letter that brings news from her aunt, who is well and happily established, wishing for Heidi to join her. Onji throws the letter to the fire. He can't conceive his life without the little girl now.
