- “Pathetic that you meet your end in a sewer, YOUNG ATLAS.”
- ―Bular exposing Strickler's true nature to Jim
Young Atlas is the tenth episode of Trollhunters.
Draal gives Jim a troll-made totem to help curb his anxiety about Claire. But Jim's newfound overconfidence leads him to a startling realization.
Jim uses a courage-enhancing "Grit Shaka" totem from Draal to help himself prepare for the kissing scene for the play, but nearly gets himself killed when he hunts down Bular and Toby must save him. During the battle, Jim discovers Strickler's dark secret.
