i LOVEE seeing him get rejected, i think i may be a masochist for it... taiskgfdfnajmgrgtkldgmr. i havent touched adwavh in a while so i cld be completely wrong abt this but i dont think jeth scars you? i think he grazes the knife near ur neck and you bleed a little (?) BUT it wld be SOOO interesting if that graze was deep enough to leave a scar (forgive me if im wrong, again, i dont remember it too well HAHA) . but speaking as if he did, i personally believe that he would leave a scar on the TO to assert some kind of mark onto them!
if he can't have them then the best thing he could do is leave his mark both mentally and physically, it may not be permanent because it could fade over time but jeth is unable to even severely harm the TO so he couldn't even leave a deeper scar if he wanted toooooooooooo </3
