This is the only scene, where Mephistopheles is really
upset and turns into a human being of flesh and blood.
Margaret showed the box of jewellery to her mother, who
"smelled" something was not quite in order with
this box. She calls the priest, who congratulates her
to have him come, takes the box and takes it to the goods
of the church. Only the church is an institution
that can take in goods that do not belong to her. Faust
orders Mephistopheles to organise new jewels that are
even more beautiful that the first ones.
