A few hours earlier, three men locate Mikasa's home and kill both her parents right in front of her eyes. She is then knocked unconscious and kidnapped. Suddenly, the robbers in their hideout hear a knock on the door and Eren comes in, acting lost. One of the robbers approaches him but Eren slits the robber's throat with a dagger. Eren also kills the second robber as the second robber attempted to attack him. He then frees Mikasa from her binds but the third robber appears and lifts Eren up as he strangles him. Eren frantically yells at Mikasa to fight or both of them will die. Mikasa comes to a realization that the world has always been cruel and that she has to fight. She immediately stops shaking and stabs the man squarely in the heart, saving Eren.

The police arrive hours after the scene along with Grisha, who hugs Eren and scolds him for his recklessness. Mikasa asks Grisha where she can make it back home, although she has nowhere to go. As a token of acceptance, Eren gives Mikasa his scarf and Grisha takes her into his family.
