Now Jon knows: Ned Stark is his uncle and the Stark kids are his cousins; he's the heir to the Iron Throne; and he's been hooking up (and maybe falling in love) with his aunt.
So he has some decisions to make.
There are plenty of risks in publicly revealing such information, the least of which is the chaos it would spark in the North, where the undead are headed and the living are already suspicious of Danerys (Emilia Clarke). And, more than anyone, Jon is Team Who Cares About Politics, so maybe he'll stay quiet in order to keep a united front in the face of the Night King.
We were also reminded during the premiere that Danerys has got quite a temper, particularly when it comes to people questioning her authority as queen. She has dragon fire for those who won't bend the knee, and she's not afraid to use it (see: Sam Tarly's brother, father). Jon's parentage threatens Danerys and what has fueled her throughout the show: the unwavering belief that she's the rightful heir to the Iron Throne.
So, yeah, Jon has plenty of reasons to keep quiet - except Jon cares a lot about telling the truth. Remember his annoying refusal to lie to Cersei Lannister (Lena Headey) when it seemed that's what was needed to form a humanity-saving alliance?
Then there's the more pressing matter of his growing love affair with Danerys. Davos Seaworth, Varys and Tyrion Lannister all gabbed during the season premiere that maybe these two love birds should just make it official already.
But now Jon knows he's sleeping with his aunt. Incest is generally a huge no-no in Westeros, and, plausibly, Jon is grossed out by it. But maybe it wouldn't be such a big deal to Danerys, especially given that the Targaryens wed brothers and sisters for 300 years "to keep bloodlines pure," as Cersei Lannister put it during season 1.
Some of the Targaryens born from generations of brother-sister couples appeared to exhibit madness. "Half the Targaryens went mad, didn't they," Cersei previously remarked. "What's the saying? 'Every time a Targaryen is born, the gods flip a coin.'"
People have been keeping an eye on Danerys to see if she's showing signs of her father's power-hungry bloodthirst, the kind that led him to want to blow up King's Landing and kill all its civilians rather than surrender to invading forces. So maybe Jon will come clean if he sees Danerys go off the deep end. "You gave up your crown to save your people," Sam tells him. "Would she do the same?"
If Jon does decide to go public, he can use the evidence Sam gathered and Bran's all-seeing powers. And, lest he not be believed, he can point to the fact that he can ride dragons with no problem.
One thing we do know for certain: All that brooding Jon Snow has exhibited thus far will only increase as he agonizes over what to do.
