Curate, connect, and discover
I have a theory that during Vat7k, Varian didn't go by his real name for a while, but rather Vee or Var. Mostly because if he were to use his real name, he would've been detained (y'know, from the whole coup d'etat and terrorism). I think that Nuru, Hugo, and Yong would've known his real name, but just thought he preferred to be called a nickname.
Idk :3
