this was incredibly written and the ending was super satisfying, but i have a couple of questions (hoping someone could maybe clear them up?)

*edit: atp this is just a dump for all my unanswered thoughts lmao pls excuse the word vomit

1) i know that lewellyn was shown to be taking sleeping pills when he was being transported between his jobs to kill targets, but was it ever stated why he had an adverse reaction when shavonne drugged him without his knowledge?

2) what happened with the candle shavonne took from his apartment... or with the candles in general? was it just a murderer gimmick thing or does it have any deeper meaning/significance in the story?

3) why were people looking to lewellyn for sex near the beginning (prostitution)?

4) did lewellyn ever actually work (i know he left the apartment complex often but i dont think it was ever mentioned where he was going)? after shavonne and lewellyn become lovers why does lewellyn still not tell shavonne what he does for a living?

5) was lewellyn really ever wealthy? and if so how did he get the money?

6) why are lewellyn's nails blackened? was it just a byproduct of his environment at lute?

7) why did turner try to come on to shavonne if his job was only to seduce & monitor shavonne (since fawkes also seemed surprised when shavonne told him)? sure, turner could just be tactless scumbag, but did he actually become enamored with shavonne? like what would the point of trying to rape him be if he actually had a life outside of the fake editing and only wanted the money?? glad he got castrated

8) maybe more of a commentary rather than a question: lewellyn was obviously struggling with some serious trust/dependency issues (e.g. believing shavonne was lying about loving him) right up until his flashback chapters because of shavonne's behavior in the past (which is super understandable), but it seems like it was just dropped/resolved without explanation later on?? like yes lewellyn confronted shavonne about his distancing behavior during the turner arc but that was later on and less about lewellyn's own mentality and more about shavonne's decisions (it seemed like lewellyn was already obedient and accepting of shavonne wholeheartedly by then)... so my question is: was this fleshed out more in the novel or is it just a flaw of the writing?
