As members of the group left behind try to make sense of their situation, Masaki, Hayato, Mitsumune, and the bus driver continue toward the tunnel. Masaki finally explains why she is adamantly against going through the tunnel, but how much of what she says can be trusted?
Even if I enter the tunnel and don't 
see it, that doesn't prove jack!
!حتى لو دخلت إلى النفق ولم أره، فذلك لا يثبت أيّ شيء
Wenn ich im Tunnel keine sehe,
beweist das gar nichts!
¡Que entre y no lo vea
no demostrará nada!
¡Que entre y no lo vea, no comprobará nada!
Même si j’entre 
et ne reviens pas,
Se entrassi nel tunnel e non vedessi nulla,
non avremmo alcuna conferma!
Mesmo que eu entre no túnel e
 nada apareça, não prova nada!
