It also could be that he's an alpha, and his omega left him or died or even bonded forcibly, the side effects could be going both ways.. cuz' he doesn't sound like an omega to me
Not to mention he doesn't have a bite mark on him, sure he could have hed them with plastic surgery,but does he have this kind of money tho?plus he doesn't sound like someone who would care about their appearance, I mean look at all those scars he has! So why would he go out of his way to hide those?

I think the skin tone is supposed to be grey. I think he’s an omega whose bond either left him or died. Which is why it panned to him in the scene where the doctor was talking about side effects of marking and the way some go crazy if left alone without their alpha. I’m not sure if they’re actually brothers or just two omegas who decided to stick together I can’t really tell.
