Nightshade's vision---what does it mean?

So Nightshade the Seer, towards the end of Outcast of Redwall, had a vision of Sixclaw standing victorious atop a mountain, but then sees a silver badger. I assume this is meant to be Sunflash's mother, but I'm not exactly sure what it means. Do her visions predict that if Sixclaw kills Sunflash, Sunflash's mother will kill Sixclaw? Visions are strange things and can be interpreted in several ways...I'd love to hear your thoughts. Argulor (talk) 20:29, October 22, 2014 (UTC)
