Rather than adding a method, why not add an observer class?

   include "observer"

   class Handler
      def update(args...)
        # ...
      end
   end

   result.add_observer(Handler.new)  # if the handler is anonymous


or

   handler = Handler.new             # if the handler is shared
   result_one.add_observer(handler)
   result_two.add_observer(handler)
