Yup! I think the King of the North will knock boots with the Mother of Dragons... And, Daenerys will HAVE JON SNOW's BABY......
No, I have not read any spoilers, nor has anyone leaked a script to me.... I know b/c Their Union is Real Magick!
Here's WHY I KNOW-
1) Jon Snow is the King of the North & Daenerys is the rightful Heir to the Iron Throne at King's Landing in Westeros... Their union will produce a Blood Heir that will be the symbolic Unification between the North & the South, and for the Seven Kingdoms to survive the War with the White-Walkers, they must unite their armies.... This seems pretty obvious to me.
2) It's Magick! ... Their union is symbolic of the two primary Elements of Creation - FIRE & WATER & Opposites Attract. Duh!
Daenerys Targaryen = FIRE ..... (She is immune to Fire & can't be burned by it b/c she is the Element of FIRE. Plus during many episodes she's been in a desert (Hot) environment, which is symbolic of Fire. Also, her first baby was stillborn & deformed b/c she didn't mate with the right guy & was impregnated by a Mortal Man. Her proper Mate is the WATER Element.)
Jon Snow = WATER ..... (Actual Snow is a form of WATER. And, most of the time he's been in a frigid (COLD) climate, which is opposite of the desert & symbolic of Frozen Water.)
... To me, the Creator of Game of Thrones knows a lot about real Hermetic-Kabbalah Magick b/c he leaves hints all over the place - like the Many-Faced God (a reference to a Magician who walks the Pillar of Mildness within the Kabbalistic Tree of Life), Faith of the Seven (Total Reference to the Seven Planetary Powers in Hermetic Magick - Sun, Moon, Saturn, Mars, Jupiter, Venus, Mercury. Even the Seven Pointed Star is draw just like in Magick.)
And, one of the main tenants in Hermetic Magick is the Eternal Love Affair between The Elements of Fire & Water in the Universe... Metaphysically, these two elements are Polar Opposites & can't help but be Hopelessly Attracted to each other....
In Magick, FIRE is wired as Electric/Magnetic & WATER is Magnetic/Electric. And, as they say, "Opposites Attract!"
3) In Magick, All of Creation in the Earth Realm comes from the Union of FIRE & WATER.
So, when these two Elements bond together something will be manifested into this Reality... The reason is FIRE is the thrusting raw power of Will, whereas WATER is the receptive power that shapes Fire's Will into something that manifests into the Earth Realm. Without Fire & Water, the physical world cannot exist.... In the case of Jon Snow & Daenerys Targaryen, their union will produce a child.
