Some time before the fall of Wall Maria, Reiner Braun, Bertholdt Hoover, Annie Leonhart, and her father lived their days in a settlement which Reiner and Bertolt would later refer to only as their "hometown". Before Annie's departure from the hometown, her father ensured her that he would support her even if all the world hated her, and that he would only ask that she would return home.
During their days spent in the 104th Cadet Corps, Reiner and Bertolt claimed that their hometown lied in the southeastern mountainous region of Wall Maria and that their town had been overrun by Titans without warning during the fall of Wall Maria. Reiner in particular expressed a strong desire to return to his hometown in the future.
During the Wall Rose invasion when the Scout Regiment recruits battle the Titans at Utgard Castle, Reiner comes close to death by a Titan and fears for the end of his life before he is saved by Bertholdt. At this time he strengthens his will, filled with determination to return to his hometown. He shares his resolve with Bertholdt, who understands the true meaning of what Reiner says and agrees with his hopeful words.
The next morning, when Reiner begins to lose hope for his situation due to an injury inflicted on his arm at Utgard, Bertolt encourages him by reminding him of their imminent return to their hometown. Not long afterwards, the two reveal their Titan identities as the Armored and Colossal Titans and attempt to capture Eren Jaeger.
