after rewatching the promo and hearing Cora say to Derek "if you want to fight and die for something do it for something meaningful" I kind of think that Peter did take back his alpha status and probably cut and run and that Derek wants to go after him to fight him for it and Cora gives that line in response(because being alpha isn't as important as what they are fighting for against Jennifer and Deucalion). Just a guess but it could fit.
