No, she was always going to be named, though for some reason back in the spring of 2017 the internet seemed to believe she was "Lt. Rainsford" for completely insane reasons, basically there was a reference to a studio in Vancouver being put into use for "the untitled Lt. Rainsford show" and despite the fact Disco was filming in Toronto, everyone began speculating that this Lt. Rainsford show was in fact Disco. Then, the knowledge that the main character in Disco would be addressed as Number One launched the speculation that at the end of the season we would learn that Number One/Lt. Rainsford was the character Number One from The Cage.
All of which turned out to be false, obviously.
