While I’m an absolute Arya stan and passionate fan, I do understand Sansa and her intentions. She is always concerned about possible lack of food or resources for the folk, Sansa is clearly upset when she asked Tyrion if they can still feed the Dothraki, Unsullied and the ‘two full-grown dragons’, because she didn’t take them into account it in the first place, but did for her family and the rest of Winterfell:
She DID take into account, that Jon will return with an army, but I highly doubt she was aware of Dany’s dragons as well as the Dothraki and Unsullied. So apparently I can RELATE to her being a little pissed about the lack of food for the rest of the army as she usually always makes sure the stores are filled.
I think it’s a great responsibility to be in charge of the resources of Winterfell and Sansa has done a great job in the past if you remember the scene in season 7, episode 3, when she was told that they didn’t have enough food left, especially not if the armies of the North come back to defend Winterfell. Sansa’s exemplarily replies by saying “Then we must prepare for that eventuality”.
She even suggests to build up the grain stores by receiving regular shipments from all the keeps in the North:
Additionally, she also requests the breastplates to be covered in leather as sort of a protection method against the approaching cold (!attentive!).
I DO UNDERSTAND that they need the army and dragons that Dany provides to defend the living, so I also understand that she is super draggy-furious about Sansa’s remark. But Sansa is the Lady of Winterfell, so she apparently wants to fulfill the requirements of that position. She is merely concerned for her people and hence a little upset about the fact that they need more resources than she initially calculated? I think that’s reasonable.
And last but not least: I think this is appropriate to say:
