Look, the only reason you really needed to watch Sleepy Hollow was "Headless Horseman with an assault rifle". But if that wasn't enough for you, everybody's favorite mad scientist is joining the fray. John Noble is coming to Sleepy Hollow! Via Deadline:

He will appear later in the season as Henry Parrish, a kind and reclusive man who possesses supernatural powers that have the potential to help the series’ protagonist, Ichabod Crane (Tom Mison).

This show just got even more exciting.
