[S] = Seth?

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I prefer:
[S] = Schiff
or
[S] = Schumer

Too obvious would be:
[S] = Strzok

Trust Sessions.

Those are all good ideas, imho, but what seemed logical to me was the [S] in conjunction with the word “Server[S]” indicated WHICH server was being referred to....”Seth’s” the one for which he gave his life - hence “[S]”

But there is definitely room for other theories at this stage of things!
