The Cup of Invincibility (1x20)

:

Henry Delachasse makes a dogs show to lure in werewolves with a silver prize cup. Two werewolves specifically, Luksos and Kerberos, are trying to get the prize cup, as it makes a werewolf drinking from it invincible against silver. Once they get rid of a werewolf's one weakness, the two intend to rule the werewolf pack.
