GoT (don't come in if your worried about spoilers obv)

[uh-oh]

first we have to keep in mind that martin believes prophecies to be phooey in the first place, and that this azor ahai thing could all be nonsense folklore of the world he created with no basis in reality.

second we have to keep in mind if it isn't nonsense, the prophecy doesn't fit anyone who is alive right now. we can make it fit almost anyone, but its not a perfect fit on anyone.

third, if it is jon, it means daenerys' death

we're still waiting on "lightbringer" the sword that comes from the sacrifice of azor ahais wife right?

either way its all nonsense

while its in the nonsense phase still, i like to think it was RHAEGAR. this still could have jon as the "hero" because he himself could be lightbringer. rhaegar sheathed his sword in his wife, (his dick) to produce lightbringer, killing her.

either way i hope the bittersweet ending is the white walkers being victorious, killing the wicked evil of man and showing them as a peaceful race taking back westeros for the remaining children of the forest
