Maybe blood related people can't truly became mates or even the pheromones smell doesn't work the same way.. Otherwise an Alpha father/son would just fuck the living shit and bite their own omega relatives at some point...So maybe the uke twin just want his brother to have a proper mate.. ..The 3 of them will most likely end up together but I wish that the uke twin would go out and find his own fated alpha ..but they 3 are cool too;)
Perhaps that is one of the reasons the other family members of omegas shun/stay away from them, to make sure that doesn't happen.
Life is stranger than fiction - I know of a girl that was being molested by the dad and brother. They got caught because she ended up in the hospital, and they couldn't stop molesting her even there.
I bet it was the cat that changed time cause u know magical creatures
