Belonging to one of Dawnbreak's founding families, Brian Flynn Cleary was born and raised within the Burning Ash Pack. Brian has issues remembering his father, though he remembered quite clearly that his mother was a wonderful woman, though he spent the majority of his life being raised by his grandmother, Siobhan Cleary. Brian's childhood was rather normal, though he eventually found himself wanting more of life. As fate would have it, he would eventually find himself in a run-in with a man name Seth Redford, who was from Dawnbreak as well. Eventually, they'd meet again back in Dawnbreak but this time as a police officer and a fireman.
Brian had a life of his own now, having married to Caroline. Brian and Red didn't seem to acknowledge the differences between them. they were both sharp-witted werewolves that got annoyed by people and their stupidity, and enjoyed drinking. For years this was the norm for Brian. This changed the night that Red found a few Burning Ash members and continued to harass them. Brian didn't think much of it, his loyalty to his family and to his friend made him conflicted. He attempted to settle things diplomatically, but as one of the members insulted Caroline, Red lashed out and started a full on brawl. Brian got separated from Red, though where Red fought destruction was in his wake.
Red was gone after that, and Brian believed him to be dead. Several years later, Caroline and Brian had gone on a date, but after a night of arguing (prompted by a stressed Brian), Caroline had too much to drink and when they returned home, announced the fact that she had an affair with Red. Initially Brian didn't believe it, he didn't want to. He just assumed she had been trying to hurt him, but the more he went through it, the more he realized it was the truth. Brian moved out, unwilling to put Caroline out of the house, and wanting to still be a good example for his children.
Brian and Caroline attempted to reunite, but Brian could never bring himself to allow things to return. He'd never truly been vocal about it, or explained why. Now Brian's days are tempered by an eternal test of patience. He works with the twins, and can hardly even speak to them without being reminded of all that's happened. He knows that he will at some point come into contact with Red again, and while Caroline still attempts to make amends, though she no longer desires to reunite with Brian, finding herself once more with the recently resurfaced Red Redford. Brian has started to spiral downhill. But there's one thing that has remaines true, and unchanging. Brian loves his family, and there's nothing he wouldn't do to keep them safe.
