“I’m sorry I killed her.”
“You didn’t kill her Sherlock….”
“Of course I did. It’s my fault she left and if she hadn’t have left, she wouldn’t have started smoking. If she hadn’t have started smoking, she wouldn’t have gotten lung cancer… And wouldn’t have died.” He balled his hands into fists and hit the wooden floor with fury. “And if i had just found that… fucking cure-!”
The soldier jumped up slightly when his flat mate pounded onto the floor with his fist. ”So that’s why… the whole time you were so enthralled in your experiments when all of this was happening because… Y-you were finding a cure.” gulped John. ”I should have known…. I’m so, so, so sorry Sherlock. And all this time I thought you were being a workaholic and ignoring the problem. I’m such an idiot.” remarked Watson as he placed his hands upon his head and grasped his hairline tightly like some sort of problematic child.
“No, you’re not. I am.”
