Honestly, I'm getting a bad feeling about the fact that feathers and Sabrina interfere with her visions, both of them are absurdly powerful, our barrier dropped a feather, Dedolere is said to be an ontological threat and now feathers is splicing timelines together or something...
There's a lot of circumstantial evidence for feathers being Dedolere, or at least heavily linked to us.
Linked to? Definitely. Of course, based on what Oriko has seen, it is also probably linked to Madoka and Homura and Sayaka.
But "Feathers" being caused by Sabrina/Dedolere? This is
not likely. Oriko just said:
"You don't understand," she says. "It's... it's wrong. You-" she jabs a finger at you. "Things change when you act. This. The future is truncated and..." she waves her hand in the air, trying to find the word. "Spliced."
Both "Feathers" and Sabrina interfere with precognition. But Sabrina does so by changing things when she acts (i.e. being immune to Fate), whereas "Feathers" truncates and splices. These mechanisms are very different. Despite our earlier fears, Sabrina was
not the cause of this situation. And Dedolere is currently inert and our witchout would signify a Bad End. So in order for this situation to have been caused by her, Dedolere would have to be capable of affecting the present from an alternate timeline or from a possible but not guaranteed future and doing other things that Sabrina is incapable of doing (splicing timelines, creating objects that don't feel witchy, blocking precognition, etc.).
It is theoretically possible that "Feathers" is Dedolere, but at this point it is much more likely that "Feathers" is something else, most likely Homucifer. The whole "timeline splicing" trick could also explain how Homucifer and Homura could exist at the same time and how Homucifer could exist
at all (i.e. the previous timeline that Homura described should not have caused Homucifer to be created in the first place, but a spliced in Homura from a different timeline
would explain the discrepancy).
So does that make Feathers the magical girl analog of Cthulhu, as a comparable entity to Madokami's role of god and Homulucifer's role of devil?
According to standard symbology: White Feathers=Angel, Black Feathers=Fallen Angel=Devil
So Meguca are good, Witches are evil, Incubaters are Chaos and we're order? That seems... off.
If you use the Order<->Chaos scale, then we're clearly Chaos and the Incubators are clearly Order. Remember that neither Chaos nor Order is inherently good or evil.
