Talk:Protego Diabolica

This makes no sense...
According to this link, Protego Diabolica is the spell Newt, Theseus, Tina, Yusuf and Flamel used when they placed themselves in a circle around Grindelwald's (fiendfyre?), and - yes, I know that in the movie, they said "Finite", but here's the thing: Protego Diabolica is supposed to create a circle of protective flames, that's what they did with Finite, the script describes it as a "purifying" fire that put an end to Grindelwald's cursed one by standing in a circle around Grindelwald's fire dragon things and creating fire by putting their wands down into the Earth. Yet - the etymology does not at all fit with Grindelwald's blue circle of flames, which was not a defensive spell by any stretch of the imagination. It was a combined test to ensure that only those truly loyal to him was sent off to Nurmengard, and otherwise used as a weapon to burn people to ash. So - what's what? Why are the description and supposed usage of Protego Diabolica so contradictory, and why does the usage of "Finite", which in the books simply makes the effect of a spell to cease without any flash and bangs, suddenly do exactly what Protego Diabolica is supposed to do?
