"Another possibility is that it's more like sight. Most people can see. If you're in a dark room, I don't think there's evidence that you're unable to store sight. You're storing your capacity to see. When we see Sazed tap a sight tinmind, he doesn't suddenly see what he was looking at when he stored, his vision now improves, implying that he stores his capacity to see, not his current vision."
(I don't know how to quote so I put it in quotations)
@Oudies
I love your thoughts on this and that analogy of Sazed's tin/sight had me convinced for a moment. Of course, all of this is speculation and that WoB could make this whole discussion pointless (per the usual, right?) but for the sake of discussion, I'd like to toss that analogy back at you with a spin.
Sazed can store his vision because he possesses sight. A blind Feruchemist wouldn't be able to because he can't store what he does not already possess. And with that logic, the "spiritual connectedness" of a Connector Ferring must be possessed in order to store it. And a "connection" requires 2 separate points. So the Ferring being 1 point then requires another point (a friend with whom they're spiritually connected) in order to store said connectedness.
So with that in mind, I'm still thinking a Connector who has lost their family and has no friends would have a pretty difficult time storing their attribute. Again, the WoB stating a connection to the planet would mean a constant connection that they can store, but like you said Oudeis, probably not as well as a highly outgoing person with a wide social circle.
Thoughts?
