Graywolf, how is is pictured in BotC #3 and #4 His soulname is Vrenn.
He recognized Willowgreen, the tribe's healer and livemate of his best friend Two-Spear. They kept the Recognition secret.
I know you are hinting that Kahvi is Graywolf's child of Recognition with Willowgreen and that she lied to her mate about the fathership. But it is confirmed (by Richard or Wendy ... someone will know who and where) that Kahvi IS Two-Spear's daughter indeed.
Must confess that I would prefer that she is Graywolf's cub (when she cannot be a badass Go-Back without "special" parantage) - would make for a much more interesting story.
