While waiting for a suspected ghost, Mr. Sessaman and the doctor Classem wait up with rifles. No shots are ever fired and the scene passes quickly.

Urin, Heidi's grandfather, smokes a long curly pipe. When she leaves Frankfurt, Heidi carries back some tobacco for him. This is set in the late 1800s so smoking was not discovered to be lethal.

Urin, Heidi's grandfather, is very gruff and can be frightening at first to younger and/or sensitive viewers.

Heidi is forcibly taken from the mountains. Urin (grandfather), Brigetta and Peter's grandmother become very distressed.
