i decide to go off a hunch and purchase some water bottles to go off into the desert
“Ok just confirming, is the dead guy the black market trader or the brother?”
A crime scene…
Alright… go ahead. I can’t say that’s moving towards warm but you go for it 
Trader.
Seeing as warm water’s character was going off into the desert with water that was likely going to live up to his name, I decided to follow just so nobody else goes missing.
well either i have to choose some word such as Shelly or i go find two stone pillars in the desert as the poem says
oh I’m trying not to laugh to much here. I mean… go ahead, go into the desert.
yeah please don’t let them get eaten
please don’t be mean and just tell me if the pillars have anything to do with it
“What does the brother do for work?”
Nah let this be a fun character interaction thingy we can waste time together
“Lol! I’m lost!”
(seriously I don’t see any puzzle clues lol)
(I must look harder)
Oh wait should we be in the game for this?
they don’t. You, as you will be with every puzzle, you’re looking for a keyword, and you have come so close to it yet so far. This is a super simple puzzle since it’s #1.
‘He uh… trades stuff’
after spending ages in the desert and finding nothing they realize that maybe the poem had nothing to do with it and return.
“Have you ever met someone called Percy mr burnette?”
After following behind (insert Warmwater’s character name here) into the desert, I realized that I shouldn’t just follow silently. That would be creepy, no? Thus I make myself known.
“You know, going out alone into the desert right after a murder happened isn’t the best idea, right?”
Oh and we’re back already nvm 
‘Percy? Never er’d of them.’
on the way we converse
“well how am i aware that you didn’t do it?”
“Has he had any enemies?”
