The Legend of William Tell - Season 1 Episode 4 Darkness and Light

A bold plan of William Tell's is to infiltrate the Citadel through his friend, the brilliant horseman Alexim - but this goes dangerously awry when Leon is caught talking to Alexim in the marketplace, and arrested.

Will witnesses Leon's arrest and seizes a Xaxian Warrior's deathwand which he takes back to the Shelter with him.
