Except LF told her that Stannis would save her. And to quote wise Oregon Ducks players: "No means no."
Lol you are a fool if you still trust Littlefinger. That dude is playing 5 paces ahead of everyone. He cares only about himself.
Not to mention they were married and it was their wedding night. I don't know about you, but usually sex was used in that time period to consummate the marriage.
The hilarious part of it all is that women don't give a crap about anything that doesn't affect women. Theon had his dick cut off, Oberyn had his head smashed in like a grape, Jamie lost his fighting hand, Kids were burned to a crisp, etc. Because it happened to their precious Sansa its totally different. Not to mention this same EXACT situation happened in the first god damn episode with Dany and Drogo. Both married to strangers to support their claim. Except Dany was old enough to where you could actually see it happen.
Long story short, this is nothing crazy for HBO and GoT standards.
