As for Charlie, well, he has always likes to hint that he knows something about Phan, but never directly shares it.
Recently though (mid 2013), he caused a twitter shitstorm with Dan when he made a joke about Dan preferring balls and Dan got pissed and unfollowed him and deleted him on facebook.
Charlie then started tweeting about it saying that his comment about him liking balls must have hit a nerve and it wasn’t his fault that Dan liked balls.
Dan then acted like he had no idea what Charlie was talking about and deleted him because he was sick of Charlie causing drama.
For example, the ‘no bunk’ tweets and the ’pope’ tweets.
