Jon Snow is Not a Twin (SPOILERS ALL BOOKS)

So I hate the the TV A Game of Thrones about as much as anyone who has read the books and understands how money grubbing scumbags in the media industry don't give a shit about fans does. And I hate show watcher theories on how it will all end or happen SOSOSO much because they just google theories that are just book based and blow it up ad act fucking stupid, and then you have 80 people reporting it and blowing up my newsfeed with garbage.

Jon Snow is not Meera Reeds goddamned twin.

The basis for this theory is that the actors look similar and they are the same age.

AND THAT'S PRETTY MUCH THE ONLY SUBSTANTIAL EVIDENCE. The show watchers never even mention Howland Reed. I think part of the original, old as fuck theory which was long ago debunked that this was based on, at least tries to work in Ned and Howland's friendship and the comradery  between the Cragnome and the Starks.

Why it's not true:
Besides the fact that it's stupid and has really no bearing on the story so why make the theory...
The Starks and the Reeds are both Northern families. They are all most likey decendants of The First Men and all lived in the area on their own until the founding of Winterfell and the rise of the Stark family. Through alliance marriages and just fucking living in the same place and being from the same people, NO SHIT THEY BOTH HAVE BROWN HAIR. But Meera has the Cragno green eyes. Jon has gray eyes. Meera is incredibly short for her age, much like her father who was unnaturally short, as are many Cragnomen. They're both good fighters...because Jon was trained with a fucking sword and Meera's family is big on hunting and spearing.

There are no similarities between the two. There is no reason for them to be twins. There is no plot point that can be helped by this because the characters are on vastly different arcs and are unlikely to meet. Meera has shown no ability to warg, no dragon dreams, no green dreams, and no prophesies or visions concern her. There is NOTHING linking the two other than their fathers' friendship and living in the same region. And I guess Bran.
