A discussion with Lihaku about recent events leads Maomao to realize that the mysteries she's helped to solve are connected. As the final piece of the puzzle falls into place, she rushes to stop impending disaster.
That's always the case with 
things that can't be undone.
الأمر هكذا دوماً مع الأشياء
الّتي لا يمكن إبطالها
So ist es bei allem,
was nicht wiedergutzumachen ist.
Y ya no habrá vuelta atrás.
Y ya no habrá vuelta atrás.
On ne peut rien faire
pour remédier à l’irrémédiable.
È sempre così
quando sta per accadere l'irreparabile.
É sempre assim com o que
não podemos voltar atrás e refazer.
И потом уже ничего не исправишь.
