A look into Grisha's memories shows Eren the many secrets his father was hiding, including one which led to his mother's demise.
If we let him run off,
the Titans we're about to make
إن تركناه يهرب، فستلحق به العمالقة
Er wird die Titanen anlocken,
die nun entstehen werden,
Balancer une proie vivante
attire les titans
In questo modo i Giganti che stiamo per creare
lo inseguiranno e si allontaneranno da qui.
