As season four begins, we find Ichabod detained by the agents who accosted him at the cemetery at the end of season three—agents who seemingly know much more about Ichabod’s escapades in Sleepy Hollow. As “Columbia” continues, Ichabod finds himself crossing another foggy road but this one doesn’t lead to Sleepy Hollow. Standing firmly in our nation’s capital, Ichabod must battle the unknown but he’s not alone.
