pierro saying "fate grants favors to no one. only those who would fight it with every ounce of their being may earn the right to challenge it" about arlecchino reminds me a lot of that one nicole line, said after scaramouche removed himself from the irminsul, which served (almost) as a prelude to fontaine.

"unfortunately, the fate of teyvat cannot easily be changed. perhaps a god may have a slim chance, but for anyone else… who can say. […] history does not change easily, but human hearts can. believe your own eyes. only that which you see is true. what is unseen is but an illusion." - nicole

this line intertwines a lot with fontane's plot and the monologue arlecchino has in the region's teasers, there's a constant conflation between performance and reality. if it relates to furina because of her story and the fate of fontaine, could it also relate to the duality in arlecchino's character - that sways between the person who reformed the house of the hearth and the fatui harbinger? moreover, her constellation "ignis purgatorius" can also extend her connection or parallel to fontaine's history. fontaine's quest had a major focus on the original sin and the cleansing, and consequent absolvition, of its people. it's curious that her constellation includes the word purgatoris, something that can relate to the place or state of suffering inhabited by the souls of sinners who are expiating their sins before going to heaven or the act of cleasing/purifying.

could this mean something more for fontaine's story as a whole or is it simply an analagous coincidence?
