Attack on Titan season 3 episode 1 Smoke Signal
Levi's squad, now composed of Eren and his remaining friends, are camped out in a cottage where Hange carries out experiments on Eren to test his Titan and hardening abilities to seal the wall. Hange reports that Pastor Nick has been tortured and murdered in the Trost District barracks but she accuses the Military Police's First Interior Squad of being responsible. Levi suspects that someone in the government has their sights set on destroying the Survey Corps and concealing the secrets of the Titans. After Nifa delivers a message from Erwin, who has been arrested by the Military Police, Levi has the Scouts abandon their hideout only shortly before the Military Police storms it. Levi figures that the government is after Eren and Historia and he decides to head back to the Trost District. Before Hange leaves with Mobilt to go after Erwin, Eren gives her a written copy of the conversation he recalled between Ymir and Bertholdt. The Scouts arrive in Trost, and Jean and Armin disguised as Eren and Historia are soon abducted. Mikasa and the others easily rescue them from their kidnappers. Meanwhile Levi is uneasy, and tells Nifa about Kenny the Ripper, a serial killer he knew in the past, when suddenly Kenny and his minions appear. They kill Nifa and the rest of her team, and then Kenny pursues Levi across the rooftops.
