Attack On Titan - Season 3 - Episode 15 - Descent [English Subbed]

Summary :- The Warriors prepare for the incoming Scout Regiment attack. At Zeke's orders, both Reiner Braun and Bertholdt Hoover put away their misgivings to focus on the task at hand. Reiner tells Bertholdt that he will need to be able to think on his own for this battle instead of waiting for Reiner to signal him, and the two agree that now is the time to settle everything once and for all.

Though the Scout Regiment later manages to incapacitate Reiner by partially decapitating his human body while he is still in his Titan, he manages to roar, signaling the Beast Titan to throw the barrel containing Bertholdt into Shiganshina District. The Scouts scatter, but Bertholdt does not immediately transform into the Colossal Titan after seeing the extent of Reiner's injuries. He asks Reiner to lay on his back to protect himself and confronts the Scouts alone. Armin Arlelt tries talking Bertholdt down, but the latter refuses and admits he only agreed to talk as a way to test his own resolve and willingness to fight them. After Mikasa Ackermann fails to kill him, Bertholdt leaves and uses his omni-directional mobility gear to ascend high into the air where he transforms into the Colossal Titan.
