Halloween is generally a challenging night for keeping order in any major city, but when a demonic outbreak hits New York on All Hallow’s Eve, the staff at the Institute springs into action in the new episode "The Beast Within." As the Shadowhunters chase their demonic quarry, however, Jace (Dominic Sherwood) can’t stop worrying about Clary (Katherine McNamara). Elsewhere, Alec (Matthew Daddario) is similarly distracted by concern over Magnus’ (Harry Shum Jr.) ongoing depression.
