rumor has it six learned something terrible about the disappearance of nine. apparently seven has something to do with it - what do you think of this?
look, we've all heard the rumours (or, the jokes, if you'd prefer) and the difficult thing is that this case is an ongoing criminal investigation - the impartiality of which has been seriously threatened by everyone having heard the rumour. And with the allegation being as... gruesome as it is, we have to remember that nobody can be assumed guilty before any evidence has come to light.
Though if it makes you feel better I should point out that nine is still like, alive. We actually hang out sometimes. It's math stuff, you don't have to worry about it. You can't really kill math!
