I have updated the gallery with behind the scenes and episode stills of Matt in the sixth episode of Shadowhunters titled “Of Men and Angels” to the gallery. You can also read the synopsis for the episode below:

With Luke in dire need of help, Jace, Clary, and Simon take him to Magnus’ lair in hopes of saving his life. Once there, the story of how Valentine came to be evil and Jocelyn and Luke’s past is revealed to Clary in hopes of triggering her memory of what happened to the Mortal Cup.
Meanwhile, Isabelle and Alec are tasked to restore their family name in the eyes of the Clave.
