Nothing like omega thingy. My interpretation is remember how Karas used to bite Abel when Karas was a kid? Well this moment when he realized he was Abel, it’s sort of like him doing the same thing. Bit his Abel again asap xD but now since he’s an adult he’s going for the neck ╮( ̄▽ ̄)╭
OHH okay thats completely slipped my mind. Yeah, karas was biting abel all the time as a kid but i thought that was when karas hadn't fully trusted abel.
So why'd he bite abel? Is this an regas' like omega's? Can anyone who has read the novel pls enlighten me ?
