Well, no offense, but I think someone has sold you a stinker on this one. I predict this will turn out to be total bollocks. I guess we'll have to wait and see, not least because a "fill in the gaps" spin off would be in production by now.
Could be. I guess we'll find out. Difficult to see. Always in motion the future is.
Also, FYI, it's to fill in the gaps between Discovery Season 2-3, not 1-2.
