Conversely, Cutter and Skywise knew their soul names already when they had that quasi-Recognition moment which we know is canon. And yet Cutter at least is too young, unless he'd somehow found his soulname while he was in the troll caverns. I find that doubtful as it's too big not to have been included in the story. I'm somewhat sure I've that heard Wendy or Richard have nixed the idea that the soul name is a truncated version of their real name. Tyleet definitely has a soul name. When she was born, Nightfall said "Hers is a Wolfrider's soul name but the tribe can call her 'Tyleet.'" And we saw it when she and Scouter Recognized and again later when she, Scouter and Dewshine exchanged soul names in the events of "Wild Hunt."
