ahhh, another theory!

so, from what i was able to take from the situation:

the author/murderer does not know whether or not the guy is blind, but he seems pretty confident and like many killers, is toying with their ‘prey’. murder for a serial killer isn’t just killing the person, it’s usually the process of getting the most fear out of someone before you do it. so, i feel as if he wants to make this guy suffer from stress and fear to the point of breaking. he finds it interesting and that is why he thinks about him even when they are apart.

to support this claim, he recognizes him as a main character, the person he refers to when he says, “unfortunately you aren’t the main character”.

the guy he was choking is yet another fan of his, it’s what we can deduce from the line, “did you lie? i was excited when you said you could make me feel good.” if some of you didn’t already notice, near the very beginning when he first gets confirmation of the appointment and is staring at his phone next to the body, the corpse’s hand has the writers callus. this would mean that the people he is normally able to murder are fans because they are the people that very easily approach him. otherwise, he would need to search for victims.

something about corpses also intrigues the author, not sure why yet. he mentions that the stronger the trauma for a villain, the stronger the motive. so, that might mean two things. he had a traumatic experience in his life involving a corpse (perhaps parent as that is usually the go to option) and it left an imprint on him, or he hates attention that he gets and finds people annoying and full of empty promises (i got this from the choking scene).

we already get hints of lots of abuse towards our masseuse, so perhaps that is also what is interesting for the author. he has trauma already, so he might’ve been able to tell from the fearful beating of his heart from the moment he entered.

either way, that’s what i am getting for now. i’ll perhaps have more in the future. sorry for referring to them as author and masseuse, i haven’t been able to grasp their names in my memory yet. i’ve always found it hard for comics haha
