Not the first time I've heard someone suggest that Dust is alive, but I don't really buy it. Not saying it's impossible, but it seems silly to me. I mean, I don't have a better explanation for what Dust is, but still, nanites?

I also don't subscribe to the idea that Grimm are Dust. There is nothing to suggest any commonality between the two...

I think the reason that there doesn't seem to be any space Grimm is because Grimm are attracted to negative feelings, and their sole motivation seems to be destroying humanity and their creations. A huge, empty, uninhabited vacuum isn't likely to attract a lot of Grimm.

Actually, the main reason that there doesn't seem to be any space Grimm is because no one in the show has been to space. You could say the same about Oceanic Grimm. We just haven't seen anyone in that environment, so we have no evidence that they exist yet. Maybe in volume 6, they'll send Cardin in to orbit and he'll be really grumpy about it, attracting a bunch of Daalek Grimm.
