At Utgard, the Scouts engage the Titans. Earlier, Reiner visits Ymir and realizes she is able to read an unknown writing. When the tower is breached, the recruits are left to halt the Titans advance. After a close call, they barricade a door.
Outside, the Scouts nearly finish off the Titans, but the Beast Titan begins throwing projectiles at them, and calls in reinforcements. The veteran Scouts are killed, leaving the recruits defenseless and lamenting their deaths. Then, Ymir jumps from the castle, transforming into a Titan.
