Extra-Holy water is Holy water blessed directly by a Pope. It gets more sanctified as more Popes succeed him. Mary had water blessed under Pope Paul III, who opened the Council of Trent. How she got her hands on Holy water from a 16th-Century Pope is another question; Yet another question is, how will she get MORE Extra-Holy water?
I hope you enjoyed my detour. It’s a nice way to break out of my routines and let my creativity loose. A downside is that it really limits how much exposition I can give. I have a limited number of panels as it is, and every time I fork the story I reduce the amount of attention I can give to any one piece. It’s frustrating, but that just means I have something to come back to some day.
Paranormal detectives will be on the shelf for quite a while, but I do hope to come back and explore this more.
