You'll never be able to do anything with that info and until now despite all of my play throughs on both pc and xbox i had never heard of the Suspected Synth quest. So based on my playing having synths hidden in your settlement other than maybe triggering that quest does nothing.Aha. I don't. I'll have to get that next time I level up. What do I do then? Is there a way to unmask them?
I'm still annoyed that I can't do anything (yet) with the info I learned snooping around in the Institute (like which NPCs are synths and which are Institute informants). Like, some of that is stuff that Piper would love to know, but I don't ever get the option to tell her.
The only sure way to know who was a synth is if when they are dead they have the synth component on them and it only appears on dead bodies, so you can't try to pick pocket them to see if they have it.
