I've read it, very interesting: you've convinced me it a sort of link too different from the Link to be considerate more than e distant relative, or not related at all.
That said, there also is a thing I'm doubtful about:

I remembered this very differently, at least from TGH: the sul'dam had something like of a "veto" on all the damane's channelling, but couldn't actually force her to do anything, and that's the reason damane need to be "trained" instead of just dragged on: if the damane doesn't actively co-operate, no weave forms.
When Tuon did it I seem to recall something odd and different, yes, but I guess I just ignored it since it didn't add up with what I knew until then :V
