Yup, got that. I like the idea of calling this the "all Is lost" moment, pointing up that the hero/ine reaches their lowest point here and can't see a way to save the day. So my hero is accused of being a traitor, ostracised by his friends, one of them tries to kill him - but he's the only one who knows they're walking into a trap, and they won't listen! Yeah, that feels pretty "all is lost"...
