Podrick is hard for Brienne.
It's only HALF incest with Jon anyway.
Which makes me wonder... If Bran can "warg" into Hodor's body, then can't Jon warg into another person as well? And if so, could he warg into a chick's body? That could make things freaky!
I'm wondering what's going to happen at Kings Landing between the Sparrows and the Loyal troops.
And where are all these armies coming from? Seems like everyone is attacking everyone, then they get attacked, and then they attack someone else, and so on. But they keep coming up with more soldiers!!
Admittedly, I personally think what will happen is Sansa will realize that Tyrion was actually a really good guy and her true "knight in shining armor", but he'll die protecting her or other people so it will be that tragedy porn Martin likes to inflict on fans so much. Either way, I doubt Sansa and Jon are going to wind up boning. I'd say that biggest problem with your idea is that warging into someone means your body goes limp so...not as freaky as one might think.
As for where the armies come from, Martin is pretty vague on numbers most of the time, but I think he's more or less following the old medieval style of things. Basically the biggest obstacle to getting an army together in medieval times was to pay for everything, you could train up a decently competent fighting force from the peasants in a few weeks or months, but they demanded pay of course.
