OKay but what if Owen was born first? What if when Digger got sent through time, he didn't go so far and he met Meloni BEFORE she and Don fell in love? What if Owen was raised by Meloni? And Don was his step dad? And when Bart was born, and Don was killed, the same lab that had Bart in the VR simulation kept Owen captive. And when Iris broke Bart out, she got both of them? And while she told Bart about his Thawne/Allen lineage, and about his Grandpa Barry, she also told Owen about his father, his real father? What if they were sent back in time together, and Owen protected his little brother? He tells Bart stories about the father he never got the chance to meet, and things about their mother Bart didn't get the chance to know. That when Max took Bart in, he went to find Digger? What if They already knew each other, and Bart was Impulse and Owen was Captain Boomerang Jr? That Bart never fought the Rogues and refused to bring any of them in because of it, and Owen may help rob banks and pull heists, but he wouldn't lay a hand on them Flashers. Those are Family. That every time he and Bart see each other, it's just a nice brother reunion and catching up.
And then Thad comes along and Owen being a big dumb himbo boy, goes ":0 Bart NEW BROTHER :D" and adopts the kid on the spot. Thad, never having a place ever or any kind of positive connection in his thousand years of life just accepting defeat, cause “maybe this orangutang wasn't so bad, unlike my counterpart”. And Owen was like their glue that kept them from killing each other until they established an unbreakable bond. Digger adopted all of them with Max as the co-parent and now they're just a happy family.
