continuing from this, I decided to try and figure out which name matches which project.
First of all, I’m 98.7% sure that Mona Wilder, the green-eyed shapeshifter, is Project Lamia. Look at this photo of Alexia Fast as Mona, wearing a Blackwing jumpsuit: (x). The symbol is only partially visibe, but there isn’t any other symbol that matches it other than Lamia.
I figured Roose Fryburn, aka the human bomb (if previous theory is correct), would be the easiest to identify.
My guess is Project Bel. While searching “Bel” will likely direct you to the wikipedia page on the Mesopotamian Bel, I think it’s far more likely it refers to Celtic deity Belenus (Bel being one of the alternative names for him), the Sun God. It seems rather appropriate for the “human bomb” Project.
For Kevin Nothiere aka the invisible guy, I’m not certain. Both Herodias and Banshee have certain qualities that could connect. Herodias "in Christian mythology of the Early Middle Ages, came to be seen as a spirit condemned to wander the sky forever [...] permitted only to rest in treetops between midnight and dawn.” (x) Banshee, on the other hand: “heralds the death of a family member, usually by shrieking or keening.”, “also predicts death. If someone is about to enter a situation where it is unlikely they will come out of alive she will warn people by screaming or wailing.” (x)
All things considered, I think it’s more likely that the invisible person would be called Banshee. After all, the most outstanding quality of banshees are their voices. And if someone is invisible, how would you know they are there at all? Their voice, duh!
This leaves Marjory Teeple as Project Herodias. Things about Herodias that we need to know: she is a mother, she took part in the beheading (which led to the whole condemned spirit thing), and she later came to be seen as one of the patrons of witchcraft and part of the sky train of witches under the name Aradia. Thus I propose that she is perhaps connected to the beheading Priest took part in, and also could be connected to either Suzie (mother&witch) or Wakti Wapnasi (Wendimoor’s forest witch) or both of them in some way.
(other possible theory: a friend suggested that Marjory could be Project Elli, considering Marjory has a bit of “old lady’s name” flavor to it. I’m, however, not convinced as a) i still think 4 names = 4 orange projects and b) i have recently started suspecting that project Elli might be one aunt Esther, because if she is alive, she must be over 50 at least, over 60 more likely)
