Well, that narrows it down to two directions, forward or behind us. [Dan nocks an arrow, aware by now that it won't do anything against the Sisters but also aware that arrows are mighty good at pinning things to whatever is behind them. And good at snapping through the thin parts of the nets the Sisters have been using.]

If it's those two laughing women, their nets have some kind of paralyzing effect. I think they get in your head like those other creatures do. [Which Dan would like to avoid again, thanks. He nudges the horse slowly forward, eyes and ears peeled.]
