i am confusion

basically sid is betraying cain by giving him (the dude with the glasses and bombs) the object cain gave to sid, and now the dude with glasses is trying to kill them (kyeongjun, doctor and the orange haired boy) using the object (it gives the dude with glasses more power)cain has been looking for the doctor to get rid of the bullet in his heart and although the doctor did try taking it out, only half of it was removed so now cains powers are slowly coming back (as u can see in the last panels. cain entrusted the doctor and the orange boy to take care of kyeongjun because cains afraid kyeongjuns life will be more dangered if he stays with cain for too long. thats how i understood the story lol ive read the raws up to chapter 85 ٩(๑❛ᴗ❛๑)۶

Thank you ╥﹏╥
