The time-traveling History PhD student that is Ros (a la Game of Thrones)

Bob K:
I'm convinced Ros is a time-traveling student working on her History PhD. Pursuant to this she is interviewing every major player about their political motivations under her cover as prostitute.
I figure she must have a colleague in Essos covering that end of things. My money would be on Dani's girl who's always saying that everything is known.

Joining the 1pct:
All of Dany's girls are dead.
It is known.
Yes, it is known (but only on TV, not the books)

Boy Howdy:
Nah, once she got sealed in the vault, she traveled back to her own time. Poor XXD died very, very confused.

Bob K:
It also makes her last conversation with Theon reminiscent of Jeff Daniels' advice to JGL in Looper.
"I'm leaving Winterfell. You should too."
"I probably will, but I was thinking of coming back..."
"I'M FROM THE FUTURE: STAY AWAY FROM WINTERFELL."
