what if he just transferred a copy of his mind into the synth child only to later use that information to come back? like even this could be thought of if the SS decides to destroy the institute, like maybe the synth child is Shaun uploaded into the synth child body only to rebuild the institute long after the SS dies, who knows.

that synth child aspect of the story bit blew me away, because it suggested that Shaun was 10 years old but later on in the story he turns out to be 60 years old, and when Shaun became the leader of the institute he waited roughly a full decade before he considered releasing the SS, this information is found in a holo tape detailing the info of the synth child via Dr. Lee and her development of the child, she doesn't understand the reasons why Shaun wanted a synth child but created it as he ordered her to do. but the author of this video brings up an interesting thought, if this was your parent, why only leave bread crumbs to get them to the institute on their own when you could just as easily send a courser and relay you there at all? but something accrued to me that the idea that the player being a synth was another experiment of Shaun's and these breadcrumbs to all the SS capabilities suggests that the SS is a synth not to mention many other things talked about in the story in the game. Shaun on the top of CIT ruins after bunker hill, even mentions when he released you that it was an experiment of sorts to release you, he sounded more like a scientist to see what you would do and it seemed he had no empathy for you if you possibly died trying to find him, and at no point were you given a direct path to the institute, it involved you having to figure it out on your own, not to mention why send you to find the very escaped scientist he wanted dead by Kellogg's hand to only figure out how to gain entry inside the institute, it just doesn't match up that you are indeed his father and are human, it all seems intentional to the end for the SS to find him, but he couldn't have known you would be able to find Virgil and that Virgil would even understand the whole molecular relay tech to begin with as he was only Bioscience. so this whole story reeks of another motive, look i know bethesda says the SS isn't a synth, but they often break the lore in their games to the point where it's possible they don't want people to believe this idea, but more and more as i play this game it sounds more than likely this was the story as there are to many things that don't quite match up with the story. it sounds more like the SS is a synth, i mean think about it, they wanted to know where the RR was but couldn't figure it out on their own and the only person who was able to find them and their extended location Ticonderoga, they wouldn't have been able to find this location without you, of course it could be argued they just tracked every location the relay sent you or alternatively it tracked every location in the commonwealth where you went, but what about the intel of the location, the institute couldn't have known unless the chip also could be used to listen in on your conversations, but if that were true, they would know when they were being betrayed by the SS long before you decided to attack them, so that doesn't make sense. i guess it's possible that their tech just isn't that advanced and it only appears that advanced, idk, i'm still working on the theory myself.
