Events proceed just as you might expect. The guard is rough, violent, and the Joker is very obviously not complaining; he doesn't say another word, but the look on his face is eloquently rapturous.

Eventually, the guard finishes up and leaves. He declines to look up at the cameras as he does so.

The Joker lies still for a while, and then dresses himself slowly, picks his blanket up off the floor, shakes it out, and curls up under it. He doesn't look rapturous anymore. He looks... tired.
