The Female Titan arc
After it is deduced that Annie Leonhart is the Female Titan, Waltz is tasked with meeting up with Eren Yeager, Mikasa Ackerman, and Armin Arlert after they successfully lure Annie into the tunnels beneath Stohess District. When Annie anticipates the Survey Corps' plan, and transforms into her Titan form inside Stohess, Waltz attempts to ask Armin if they are going to use Erwin's backup plan, but is crushed underfoot by Annie.
