This post contains spoilers. Side effects may include false hope.

Every “Game of Thrones” fan has a gut feeling about what to make of the season five finale, “Mother’s Mercy.” As Jon Snow lay bleeding on the ground — looking awfully dead, I might add — theories started pinging around the web, and certain truthers couldn’t believe yet another beloved character was done for. The desperation was palpable.

But what is the evidence telling us? Let’s find out with a round of CSI: Seven Kingdoms. (Cue David Caruso whipping off his shades and saying something profoundly nonsensical like: “Game of Thrones?” <> More like Game of Bones.)

We might learn some new information at Friday’s Comic-Con panel — which will not have either Kit Harington or George R.R. Martin in attendance. But here’s what we know as of right now.

Kit Harington’s hair is long

Exhibit A is a series of photos taken of Harington (who portrays Snow) during Wimbledon last weekend. Harington has been vocal in the past about disliking Jon Snow’s long radiant locks, so you’d think he would chop them off as soon as his contract allowed. Why then does he still have all those magnificent curls? Curious.

Harington has unequivocally stated he isn’t coming back next season

Here’s what Harington told Entertainment Weekly:

“Quite honestly, I have never been told the future of things in this show, but this is the one time I have. They sat me down and said, ‘This is how it is.’ If anything in the future is not like that, then I don’t know about it – it’s only in David and Dan and George’s heads. But I’ve been told I’m dead. I’m dead. I’m not coming back next season. So that’s all I can tell you, really.”

Hollywood Reporter and IMDB are potentially flawed crystal balls

Last year a Hollywood Reporter story claimed that Harington and other “Thrones” A-listers had renegotiated their contracts through season seven. Harington, however, has disputed the article.

Meanwhile, Harington has been cast in one upcoming film, “Brimstone.” His “Thrones” shooting schedule gave him little time for movie making, so if he was slated to film numerous projects in the next year, that would give us a solid clue that his schedule is freeing up. As it is: inconclusive.

Jon has multiple, highly convenient opportunities to be resurrected

How opportune that right before Jon Snow was attacked, Melisandre showed up. We’ve never seen her bring someone back to life, but we know other Lord of the Light followers can. Meanwhile, there’s the chance that he could warg into his direwolf, Ghost. Again, we’ve never witnessed him accomplishing this, but Bran did it so it’s not without precedent. Then, of course, we have to consider the soulful looks Jon exchanged with the Night’s King. Could Jon end up fighting for that ice-covered maniac?

According to showrunner Dan Weiss, “dead is dead”

Weiss told Entertainment Weekly: “We would hope that after seeing the scene and the way it’s shot that the answer to that will be unambiguous in the minds of the people watching it … It should be pretty clear what happens by the time you’re done seeing that scene. It’s not an, ‘Oh what just happened scene?’”

But George R.R. Martin has made some cheeky comments

Martin’s most recent book, “A Dance With Dragons,” ends the same way “Mother’s Mercy” does — with Jon Snow dying from stab wounds. But Martin doesn’t seem nearly so certain about Jon’s fate. “Oh, you think he’s dead, do you?” Martin said during a sit-down with Entertainment Weekly.

Some other people who don’t really know anything also have opinions on the matter

Maisie Williams, who plays Arya, thinks Jon is dead. “People are really hurt by it, but that’s what this show does,” she told People. “If you haven’t learned that by now, well, I can’t help you.”

She has a point.

Emilia Clarke, however, is undecided. The woman who plays Daenerys Targaryen gives Jon a 50 percent chance of survival. But take that with a grain of salt. “I can, with all honesty, say I have no idea what’s happening,” she admitted.

The DNA evidence is telling

Book readers know that Jon’s parentage has been the subject of much debate and one dominant, not-at-all-crazy theory has emerged that would make Jon an eligible candidate for the Iron Throne. Why would Martin float such a tantalizing mystery if it wasn’t going to have some bearing on the story?

The whole point of “Game of Thrones” is to crush our spirits

Horatio Crane probably wouldn’t approve of this, because this is more emotions than evidence talking, but let’s be real: Week after week, we tune into HBO with the hope of some positive development, and time and again we are instead met with scenes of rape, murder, brutality and humiliation. The likable protagonists either die prematurely or turn out to be the kinds of people who would sacrifice their precocious daughters on a fiery pyre. And the most sadistic characters outstay their welcomes by at least three seasons.

So what does any of this mean? It’s so obvious. We’re missing one key piece of evidence: George R.R. Martin’s sixth book, “Winds of Winter.”
