"A-Alf-Alfie..." A small noise emerged from Joes quivering mouth, more tears escaping from his bloodshot eyes.
"What? Wh-What is it? Joe. You're scaring me. Whatever it is, you can tell me."
Joes whole body shook, as he uttered the two words that he wished he would never, ever have to say, in his entire life.
"Zoes dead."

Zoe Elizabeth Sugg was found dead, at 10:09am on a cold, Tuesday morning.
The news spreads like wildfire, across the world of social media, everybody is completely distraught and shocked to the very core.
But the question, that everybody wants to know, remains unanswered, and causes deep suspicion amongst the youtubers, and the viewers.
