Oh, it's been ages since I've read Pullman. But I don't think we can ascribe the portal thing to the blade, nor has there been any hint, from a metaphysics perspective, that anything like that is possible. It's got to be Semblance, as far as I'm concerned, with exotic Dust an order of magnitude less likely in second place. And there's likewise been no hint of alternate realities.

Nor would Raven be able to send them off in different directions. They have schooling to complete. Summer's gravestone is p>.95 in Patch, with Ruby visiting in winter. "Red" is already canon, anyway, and took place prior to the series, as did all the trailers. This we've known for a long time.
