There is no turning back once the Plaga has turned into an adult in the body.

The Plaga parasite will not die unless the host dies. There's no cure. Perhaps, Sr. Salazar may
have been vaguely aware of the Lord's plan all along. But it's so hard to tell.

Nevertheless, there's nothing I can do about
it now.

I have served the Salazar family for generations.
I am prepared to continue my services until the very end.
