real question for her then. as your Irri is politically saavy and known to dothraki culture, she could be a great tie in between dothraki and westeros and to disseparate the bad propaganda they have. do you think she would be comfortable in a position as a quasi-ambassador in a way? specially when Dany is queen.
I think she would thrive in a position like that. She's the perfect person to do it, especially if we go by the assumption that Dany is going to unite the Dothraki as a whole like in the show; in that case, they will certainly need someone in that position more after migrating to a strange land and having to adapt, and the Westerosi having to adapt to them as well. (Some might return to Essos, but I think a portion would stay, which will lead to some logistic and cultural issues that need to be dealt with for both parties.) It would be a natural progression of Irri's old role, which was to teach Dany about the ways of the Dothraki, so we already know she's suited as a teacher. And with how I write Irri, I think she would adapt very quickly to the different courts in Westeros and be in the perfect position to bridge that gap between cultures. The needs of her people can't be left to the Westerosi lords who know nothing about them, and who better to represent them and advocate for them than one of their own?
