X, Sid-Rail Musk, and Young Chopsie

Musk appears to just call this baby X and views him as a sort of protégé. So now, Musk and Grimes break up not too long after this baby is born. That did not stop them from having another baby by a secret surrogate. This baby's name is Exa-dark, Sid-rail Musk. I don't know what any of that means, but that baby... I don't even know what gender that baby is. It's a girl, I believe was born December 2021. There has been, as far as I know, no public explanation over the name of this child.
