Why do so many people think that Jon and Val will be a thing?

They can raid the stores of the Shadow Tower. And then push on raid the lands of the clansmen ... which are completely defenseless. As well as most of the North. All the villages are ripe for the taking.

The clansmen don 't have big stores and it is a bit unclear if the wildlings and clansmen are really enemies.

And what do small villages matter for thousands of wildlings? No matter what arguments you use there is no reason not to attack CB that is a few days away from them. And they can even win reinforcements when other wildlings see them...

If they were only about Ned's little girl and the Freys then they should already go home in Theon 1. Do they go home there? No, they don't. They also want to bathe in Bolton blood, by the way.

Actualy theon 1 ends with the clansmen wanting to talk to stannis. They can want to go home. And probably that is their wish. 

And with farya freed and their present conditions there is no reason to attack winterfell.

If they left Stannis before finding out about the Weeper then this would be two unconnected things.

Exactly. I am just saying they have to be near the wall when the weeper breaches through. Otherwise a big area of the north is lost and we havo no idea how long it would take to regain control or if the boltons or manderlys would be able to do it.
