Life as an Alpha has always been viewed as the easier path; Alphas are the top of the food chain, lead the packs, and are the deciding force in the world.
However, that's not the case for all Alphas.
Luke is viewed in his new pack as a strong warrior, but that wasn't always the case. In his previous pack he had to work his way up in order to keep from being tortured by the Alpha and being viewed as weak. Now that he's in a new pack with his mate by his side,
Luke is confident that he can push away his past and move up in his life.
Tan has always been an Alpha who others viewed as a wrongly placed Omega. He never acted cocky or dominant, unless his wolf was angry and controlling him. With his mate, an Alpha much more dominant than himself, Tan is sure that he can finally stop hating himself for being a weak Alpha and feed off his mate's strength.
