People were claiming for years Wano would be Zoro's arc and his entire family history gets addressed in a SBS
No, really, why wouldn't that have been included in the main story instead of all those chapters wasted showing people running to the roof or the basement?
Same with Tama. And as I said back then, I was certain Oda would address Hiyori's line in the SBS because it was ambiguous even in Japanese. Looks like he didn't go as far as changing it to include "Orochi" though.
As for Tama being a Kurozumi, I doubt anyone in the story would care, but it is sweet irony that she was perhaps the biggest contributor to Orochi's defeat.
