<Snipped quote by Lord Wraith>

Well, yeah, in real life, there is no excuse for killing. I'm just a VERY BIG CSA fan. Thomas IS Bruce Wayne's Earth-3 counterpart, but on Earth-3, he's Bruce's older brother; DNA wise, he's a Wayne. Food wise, both he and Bruce stick to a regimented diet to maintain their physicality, and they both wear expensive suits-Thomas not so much now thanks to, y'know, prison-and their Owl-and-BatSuits are completely different.

The prison and the fact he would be subjected to prison food (no Kale shakes for you Owlman!) should be enough to change their smells. They would be some base similarity but I can't see it being too much.
