TRANSCRIPT:
Hello, this is Wren, claims adjuster for the Dead Letter Office of *******, Ohio. The following audio recording will serve as evidence for Conway’s case. Public release of this or any other evidence is strictly prohibited. Some names and facts have been censored for the protection of the office. 
As we’ve previously established, forward and backward are not necessarily stable concepts. So let’s begin today by looking at the next letter in Conway’s backlog, which may give me insight into what happened to him.
Dead letter 14417, a long note written on several folded pieces of printer paper, sent by a Stephen ***** to his mother in late 2016. The letter reads as follows. 
NARRATOR STEPHEN: Hey mom.
Did I ever have a pet growing up? I know dad never wanted one and then Dave was allergic. It’s getting harder to remember if this actually happened or if it’s a vivid dream that’s stuck with me through the years.
Before high school hit me like a semi truck, you’d let me bike up to the arcade at the Deerland Mall on the weekends. 
LOUDSPEAKER: “WELCOME TO THE DEERLAND MALL, YOU’LL GO BUCK WILD FOR THESE DEALS! Our store hours are: 9am to 7pm” *slowly fades out*
NARRATOR: I remember the huge globe of stale gumballs loitering in the foyer. I’d chew on them even though I knew they were rock hard and would probably cut my gums up. Sorry about the quarters missing from your purse. Then I’d stop by the candy store and get a big bag of sweaty gummies that had been sitting in the foggy display case for god knows how long and a tall cherry coke from the concession stand. 
The light gun shooters and fighting game cabinets there were cool enough, but my favorite was the racing game. It had a whole mock driver’s seat that moved side to side as you steered. It was also more expensive to play than the others, so I’m sorry about the missing dollar bills. Whatever change I had leftover after a few laps of hairpin turns went into the vending machine full of capsule toys. Since I couldn’t get a dog, I was desperate for one of those new Tamagotchi toys. But where was I gonna get a whole twenty dollars? Coincidentally, the top prize advertised on the machine was a bright blue Tamagotchi. I was old enough to know there was probably only one in there, if any at all. I knew I’d probably end up spending more than twenty dollars trying to get it, yet here I was pouring money down the slot anyway instead of saving it up to buy one.
On a particular lazy afternoon, the arcade was empty: not too uncommon for a summer weekday. I put two quarters in the slot on the capsule machine, twisted the tough old crank, and out dropped a peculiar toy. The capsule itself was identical to the others: a translucent plastic casing, a bubble with a colorful top that popped off. Almost like an acorn fallen from a petroleum tree. But what was inside the case gave me pause then, and still makes me uneasy today.
I cracked it open under the flickering lights of the arcade. Inside wasn’t a Tamagotchi, but rather an egg: bigger than a robin’s egg but about the same color with a few white spots, and surprisingly heavy for a toy its size. What’s a thirteen-year-old boy want with a plastic egg? Waste of 50 cents, I thought. I put it in its case and set it on top of the claw machine so I could go play a game about shooting aliens in area 51. I was winding down a blocky corridor when I heard something behind me. I had thought I was the only one in there. I froze, and a bead of prickly sweat rolled down my neck. I turned my head to the entrance of the arcade. Nobody there. I scanned the stained carpet for anything o
