With little care to not 'accidentaly' push the keys further away with his feet, the man in black comas back on the stage, with a pair of simple devices, one for each female on teh spot ligth, he had used one before only to see it being shreded to pieces.

He places a leather hood over the head of Louise, who can't to anything to stop that from happening. The hood has a hole for the mouth, so the gag can be fitted easily.
The model of hood used doesn't use chains and padlock, but a simple zipper and belt straps.

a similar one is placed over the sweaty head of the upside down girl. all the straps held tightly in place.
