Ep 18. Forest of Giant Trees / The 57th Expedition, Part 2

Eren Yeager and his fellow Survey Corps comrades continue their mission in the Forest of Giant Trees, as they desperately search for answers about the Titans and how to defeat them. The episode kicks off with a tense standoff between two factions of cadets, following the death of Marco in the previous episode. Jean, Armin, and Connie successfully diffuse the situation, and the group continues on their mission.

As they delve deeper into the forest, the tension between the Survey Corps and Military Police becomes increasingly palpable. The Military Police refuse to provide support, leaving Eren and his comrades alone to face the Titans.

The group encounters a new type of Titan - one that is able to move during the day and break through the Survey Corps' reinforced walls. This poses a significant threat to the group's safety and adds to the urgency of their mission.

The expedition also has a moral dilemma when it comes to the fate of an injured comrade, who has been bitten by a Titan and is slowly turning into one. As they debate whether or not to end his suffering, the group is ambushed by Titans and forced to flee.

The final scene of the episode sees Eren and his comrades run into another group of cadets - one that was presumed to be lost in a previous mission. This encounter adds a new layer to the mystery of the Titans and the world that the characters inhabit.

Overall, this episode is action-packed and raises important ethical questions about the cost of fighting against the Titans. It sets up an interesting dynamic between the Survey Corps and Military Police, while also introducing new twists and conflicts that add depth to the show's overarching plot.
