It was just dumb luck Thancred managed to evade the Silence spell, though the appearance of the appendages certainly took him by surprise. He took a moment to refocus, eyes flicking over to see what he could take advantage of. Better to keep some ammunition with him, if she should use Silence again, he decided, but if they could still keep Yunalesca occupied, so much the better. He casts a thunder-based ninjutsu before looking for an opening where he can strike a direct blow.
