The official synopsis of episode 6 reads as follows:

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.

Meanwhile, in episode 5, Clary and her friend Simon were kidnapped by werewolves, who disguised themselves as police. Simon, who is slowly transforming into a vampire, broke his cuffs and called Jace for help. Panicked by the chaos, the werewolves deserted the building, but locked Clary in a container where she is likely to reunite with Luke.

Jace on the other hand, misjudged Luke as an enemy and landed a few punches on him, before escaping along with Clary and Simon, however, in a twist of tales they were trapped by werewolves. Nonetheless, to their surprise, a black werewolf appeared before them and killed the leader of the evil wolf pack. Later in the episode, it was revealed that the black werewolf was none other than Luke, who had promised Jocelyn that he would protect her daughter.

Going forward, it will be interesting to see how Clary finds the treasured Mortal Cup with the help of Alec, Jace and Magnus in Of Men And Angels. Shadowhunters airs every Tuesdays on Freeform, the new name for ABC Family.
