Chase takes the suppressants and YEETS them out the window and goes like “you’re spending my ruts with me”. Josh is flabbergasted and Chase doubles down and says that “you need to spend your heat cycle with me too” and proceeds to FLOOD the room with his pheromones to make Josh dizzy. Chase takes that as confirmation he really is an omega. They kiss and have sex.
Though, while doing the deed, Chase gets jealous and asks who left the mark on Josh’s ear but doesn’t want to hear the answer and instead just vows to kill whoever it is LOL.
So, yeah, it’s revealed he’s an omega but Chase still doesn’t know he’s the one who marked Josh nor that he is Pete’s daddy. Not yet anyways.
