masked

This is completely improvised and rather scary.
The masked person has added conflict to a cosy world. She is different, indifferent to them and helping herself to the sea cheese and pasta (don't ask) At first they all retreat into a middle sized bubble and put up barriers (literaly) Later they capture the intruder and put her in a giant bag. Next they open the bag remove the mask and put their own ' identity costumes' on her. They appear to have only good intentions.
She is forced into being one of them.
She dances with them and they are cosy again.
How does the stranger feel?
