Rare Alpha (y/n x dean winchester)

Okay so we all know about the alphaxomega verse but there is something we got wrong.
Omegas are not the rare and weak species, Alphas are the rare fruit instead.

An alpha is not defined by having a strong personality, an omega can be just as fierce. What makes some alphas rare is that only a very small percentage are genetically capable to knot. This makes them very wanted and a great earnings for the black market.
