I caught a little bit of the last episode. They are all in a grave yard fighting some kind of spirit. The headless horse man is approaching the spirit, when Ichabod yells, "Hey horse man" and he turns towards Ichabod.
Ichabob then tosses him a weapon, of which the horseman catches it and kills the spirit.
Questions;
1. If the horseman is headless, how did he hear Ichabod yell?
2. If the horseman is headless, how did he see to catch the weapon?
