at least three different secret tunnels, one for each Wall. The tunnels are
connected to some place/places outside the walls where people or titan shifters
father, Grisha, was a titan shifter. He definetely knew something about titans
and the walls since he knew about Rod and his family’s powers. Hannes told us
that “there was this epidemic disease in Shiganshina, but one day doctor
Jeager came carrying the medicine that saved everyone”.
Grisha created the medicine by himself, I believe he went outside, using this
tunnel, and got the medicine from the “Outer world” (whatever there is outside
the wall, a village or something).
Where’s the entrance of the tunnel of Wall Maria? Of course in the basement of
Grisha used it to get the medicine, he wanted to tell Eren about it as soon as
Eren said he wanted to join the Survey Corps to get outside of the walls and to
The key he
gave him opens the entrance of this tunnel.
2) Where’s the second tunnel, the one of Wall Rose? Of course under the castle
In chapter 38, the Survey Corps get to this castle to rest. They immediately
notice something weird. It looks like the castle had been a shelter for some
kind of “smugglers” who brought inside the castle lots of weird foods and
this bottle of wine. On its label there are words written in a language that
the Survey Corps can’t read. And there’s canned food, again written in some
weird language that doesn’t belong to the walled world…but that Ymir
this food and wine aren’t from the walled world, but from the world outside the
walls, probably from the same place where Ymir used to live.
How did it get inside the walls?
Reiner says this while searching for titans inside the castle
this means for
me that in the dungeons of the Castle of Utgard there’s the second tunnel that
somebody used to get food and drinks from outside. Who is the one who knows
about this tunnel and used this castle as a shelter? Probably another titan
shifter, probably the one who transforms into the Ape Titan. That’s why he tried
to kill off all of those who were there, to prevent the Survey Corps from
discovering the entrance of the tunnel.
3) Where’s the third tunnel, the one in Wall Sina? I’m not so sure about this.
The fake king here has near him the same bottle of wine the Survey found in Utgard.
This means the king is drinking a wine that comes from outside the Walls.
whoever gave this wine to the fake king, got it using the secret tunnel located
inside Wall Sina. The entrance could be in the underground city, inside the
mansions of one of the nobles, or of one of the people of the Wall Cult, or
maybe inside Rod Reiss’ mansion or inside the huge cave where Rod Reiss turned
himself into a titan.
How did Rod Reiss get all of those bottles with titans’ serum? What if he, or
someone for him, went outside to get them?
Atlas: the Titan god of endurance and astronomy, he was the first to teach mankind
astronomical science; one of four children by Iapetus; he sided with the Titans during the war with the Olympians, and was sentenced by Zeus to replace the original four pillars in holding the heavens and earth apart; one account tells that he later met with Perseus, who turned him to stone using Medusa’s head, and he was relieved of his burden at last
