HE KNOWSSS, he wasn't sure at first but he became certain when he called out "Apel" while Abel was sleeping and Abel knew it was Karas right away. So I'm guessing Karas is already certain about him being Abel
THE WAY I SCREAMED WHEN I READ THIS PART IN THE NOVEL AKDHKAHD And Karas will test Abel again if he's the 'real' abel. And karas' reaction was so cute imo
please I NEED SPOILERS spoil me
Idk if they’re talking about the same scene but Karas and Abel will be sharing the same room on the ship soon. Karas and him will talk yada yada and Karas will say something like there’s the spider behind you (the very same spider, i forgot the name, that made OG Abel so scared and pass out in the forest in past). Abel was so terrified when he heard Karas say that that he, again, passed out from fear xD andddd that’s how Karas immediately knew this fairy was Abel. As soon as that realization clicked, he hugged the passed out Abel and bit his neck, making a bite mark and saying something like “mine” or what’s mine is back ლ(´ڡ`ლ)
Ahhhh omg omg what chapter is it?
it does seem like karas is semi aware that this blond haired dude is abel
because saying reincarnation isn't real after seeing a fake of himself is something abel would totally do and karas is aware of that, including the fact that abel has such a distinct personality
