The one mercy in this was that his arms might be pinned, but the Cloak was free enough to wiggle, especially when Stephen flexed his hands, gave a small gesture and a magical nudge. It wasn't entirely happy billowing out, trying to force a bit of distance between them. To no avail.
Someone - Stephen couldn't see who - tried to interfere, and the naked man clung tighter; Stephen actually gave an unhappy little cough, his ribs aching. "This is hardly his fault," Stephen said. "He is under the effects of a spell." Which would probably get whoever it was to back away faster than he would when he realized that he wasn't doing any good.
