(...offer for rescue...), dark, subdued, vague, like all offers of that kind. (He knows that...) 
(...te friti lenu terckape sidju...) noi tai ki le'e nunfriti cu manku zi'enoi xablau zi'enoi nalsatci (.i ki djuno...)

Do I need to make the modal sticky in order to refer to all (parts of?) the relative clause(s) joined by {zi'e}?
If yes, have I to undo stickyness at the beginning of the (normal) following sentence, or is this unnecessary because it is referring 
only to the relative clauses (and there's no more relative clause to follow)?
