Read it again.
"Georgiou must either be connected to her in a chain of succession or might want to create that connection....."
He didn't give a straight answer. She could be, or she could not be.
He does give possibilities if she was.
He also says his tweets are not canon because it wasn't said on screen. Though we're in the lit subforum, that isn't a problem lol
But, he does make it clear Iaponius was included due to Sato. It is an on screen thing that was included, even if we don't know what that connection actually means.
