Okay, fine. Since you’re so curious: Jon Snow is fully back by Season 6, Episode 2—“Home.”
He’s not quite himself, though. He’s got the thousand-yard stare. You know, the look of a man who just took a dirt nap for a couple of days.
But after that? He’s kicking butt again. He becomes King in the North. He fights the White Walkers. He even… well, you know the rest. No spoilers there.
So, To Sum Up: No, He’s Not Dead in Season 4
I’ve heard people say he dies in Season 4. Bless their hearts. That’s when the Battle of Castle Black happens. Jon gets a knife in the back eventually, but not yet.
Season 4 is all about him being a hero. Season 5 is about him being a martyr. Big difference.
If you want the cold, hard truth: Season 5, Episode 10. Write it down. Tattoo it on your arm. Frame it next to your dragon egg collection.
