I'm having trouble living right now. It's been almost a freezing month since ONCE came out, and I'm not fairing well, then again, who is. SNUFFBOXES!!!!! Hehe that was auto correct but I'm keeping that. Okay back to the ranting. I HAVE WATCHED THE SCENE WHERE KILLIAN DUES OVER TEN FREEZING TIMES!!!! AND I CRIED EVERYTIME!!!! Okay, almost everyone I've met has either disagreed with a passion, or we agreed to disagree, I STRONGLY believe that EMMA DID NOT KILL KILLIAN!!!!!
Here is my reasoning.

Arthur killed Killian when he struck Killian with his sword. Then, Emma turned him into a dark one, therefore tethering him to immortality. Later, when Killian sacrificed himself *starts sniffling uncontrollably* , and yes, Emma did stab him, BUT THAT'S NOT WHAT KILLED HIM!!!! She un-tethered tethered him from the darkness, meanwhile he was no longer immortal. So Killian was already on the verge of death when he Emma stabbed him. Yes she stabbed him, but he was already dieing. ARTHUR KILLED KILLIAN!!!!

Thank you for your time.
