[Arya is beginning to border on the hysterical, but Polly keeps her cool. To a degree. There is only so long that she can maintain something softer and gentler. Polly is angry on Arya's behalf and at herself for not entirely protecting her.]

Arya Stark, enough, [Polly's stern, not allowing for any room for anything beyond adherence.] Right now, I bloody well don't give a damn what you do or don't want to do. Right now, I want to see to it that the arsehole who was stupid enough to harm my lad is dealt with to set things right.

I told you that I would be looking out for you whether you liked it or not and I damn well meant it. So, you best be a smart lad and do as I say because I won't say it again.

Get a hold of yourself and listen to me: you'll get your arm back. I will send for Jean and she'll reattach it. But I'm not budging from this spot until you tell me what happened.

Am I understood?

[If there's any doubt about Polly Perks' rank, it should be quite evaporated by now.]
