Comment by beomsyitties on Dear Benjamin - Chapter 2

@beomsyitties Basically it's when the alpha's deck swells or locks into the uterus of the one's they're packing with. Since isaac was in a heat and Benjamin was prob in a rut the knot made isaac pregnant (which is always the omega reverse babies happen) hope that's explain!
