This was a crossover with Bones. Abby and Ichabod were also on Bones. Basically on Bones the skull of a British general was used to kill a girl. Fast forward to Sleepy Hollow and Pandora brings the said general back to life. This guy hates Ichabod with a burning passion. Jenny and Emt guy get into some trouble. They have to give some shard to a guy so that he will talk to them. Abby now has to investigate her sister because of this. They end up defeating the general and his army with greek fire. It turns out that Betsy Ross used the greek fire back during the Revolutionary War and caused the Fire of Manhattan. Pretty cool. Ichabod has a dinner date, so that is nice. This was a pretty good episode I loved the zombie soldiers. In the next episode Ichabod and Abbie come face-to-face with Pandora. Battle Time.
