Look on the season 6 page of this very wiki. It says William Clayton in the "Recuring characters".

Also yea Samantha probably doesn't want Oliver in her life because of what happened with Damien Darhk last year, Oliver didn't want them in his life because of it, but then Adrian Chase happened. It's clear now that no matter where they run the threats to Oliver's life will always find them and she can't blame Oliver because he chose the life of a vigilante before he knew William existed. So I can still see Samantha relucantly deciding to move back to Star City knowing that Oliver can protect him better if living there.

I hope you're right about Ted Kord.
