For everyone curious, "acta est fabula" is the screen you get when Fiona dies in Haunting Ground (a survival horror/clock tower-ish game that I highly recommend by the way, if you like that genre)
As for characters dying, yeah it sucks, specially when one gets attached to it xD. I guess I never found this character in particular appealling enough. He was always way too wary/cautious to the MC which never worked for me. But I understand that it fits perfectly with the rest of elements of the story so nothing can be done :P
