A big part of “Shadowhunters” Season 2 will be devoted to finding Jace (Dominic Sherwood) after he joined forces with Valentine (Alan van Sprang). Clary (Katherine McNamara) will be involved in the search, but she’s not the only one who will find Jace’s disappearance difficult to deal with. Jace’s disappearance will also take a toll on his parabatai, Alec (Matthew Daddario).
