Just a warning: This article goes over a plot point from the Far Harbor DLC. There’s dialogue and plot spoilers ahead. If you’ve not explored the conversation yourself, we suggest you do so before reading this. Either way, you’ve been warned!
So Far Harbor, the most recent and biggest Fallout 4 expansion yet, focuses on you traveling North to an island covered in what the locals call “the fog.” The fog is basically clouds of radiation that cover most of the island. The only exceptions are places that have the fog condensers, which basically suck up the fog and turn it into liquid.
Your goal is to find Kasumi Nakano, who’s ran away from home because she believes she’s a synth. She meets up with a synth colony on the island, run by a prototype synth named DiMA. You’ll notice immediate similarities between DiMA and Nick Valentine.
You soon realize that Kasumi is with the colony and can be visited at any time. However, DiMA makes the suggestion that perhaps finding Kasumi isn’t the only reason you’ve gone to Acadia, the synth colony. He proposes that there’s a chance that you, the player, are seeking answers about yourself. That maybe, just maybe, you’re a synth.
It’s something that sounds crazy on the surface, but without a doubt, most Fallout 4 players have thought about once or twice. DiMA proceeds to quiz the player through more dialogue about a few curious leads that might point toward you actually being a synth.
He starts with the first thing you can remember. Interestingly, the protagonist doesn’t recall some fond childhood memory. There’s nothing from the war, provided you’re playing as a male, and nothing from being a lawyer, for the female. Not even the birth of your son, Shaun, is recognized. No, the protagonist’s first memory they have is that of the day the bombs dropped. It just so happens that it’s our first memory of Fallout 4 as well, as it’s the first bit of gameplay there is.
Provided you have Nick Valentine with you, DiMA and Nick will have a very interesting conversation. It turns out that Nick and DiMA were both prototypes over a century ago and were tested on at the same time. DiMA calls Nick his “brother.” Nick’s memories are all of an actual person, named Nick Valentine, a pre-war cop that had his memories voluntarily tested on. They got placed in the Nick we know, and boom, he’s now Nick. What if the same is true for us? We have this one memory of pre-war America and now believe we are *insert whatever wacky name you chose for your character here*.
Sure, it’s a long shot, but hey, it’s still plausible. Bethesda said throughout the game that ANYONE can be a synth. The protagonist is certainly not excluded from that statement. I’m sure in time, if we are a synth, it’ll be revealed in later DLC. For now, we can only imagine.
