Yeah as soon as she said it I imagined it must be a popular theory by now lol
But to me that brings the question of why they'd want Deku's quirk since as far as we know he'd likely have something like mild telekinesis or fire breathing or something in between right? Unless his father is more complicated than what we've been told and lead to believe
And with Shigaraki hailing from Nana and her bloodline that begins to sound to me like we're going the Deku is related to AFO route and I'm not sure how I'd feel about that
