Noooooooo! The season five finale of the HBO hit series' delivered one of its most devastating deaths: Jon Snow (Kit Harington). Yep, they actually freakin' did it, with Jon being stabbed to death by his fellow Night's Watch brothers who didn't approve of Jon's mercy towards the Wildlings. And having young Olly, Jon's protégé, deliver the final stab? Too. Freakin'. Much.
Thankfully, our heartbreak didn't last for long, as Jon was brought back to life the next season. But, at the time, we knew nothing. So, it still hurt.
