Jesus Christ Cyaloom don't join the club of people who cannot read. Lisa said, and I quote the exact words (I should remember them, you know, I WROTE THEM): "the archeologist knew more about the dead professor than I do". This, unless english grammar has been dramatically altered since I last studied it, means that, according to Lisa, the archeologist knew something about THE PERSON WHO DIED, not about HOW HE DIED or WHO KILLED HIM. And that Johnosn knew Tenjo is something now everyone knows, on the account of, you know, ANNA HAVING JUST SAID THAT IN FRONT OF EVERYONE WHO WOULD LISTEN.
There is no hint, in Lisa's words or anywhere else in the "After School" topic, of Johnson being implied in the murder. I should know, I planned and wrote the whole thing. So please, for the sake of my sanity, let's end this discussion here: making any sort of conjecture about the identity of the killer, or even about who could know something about it, or even about who could know who could know something about it, is metagaming for everyone. PARTICULARLY for Omega given that he was the one who obtained the less info. The sole exception, the only one who actually knows something about how Tenjo died, is Kaito, but he already stated he will share his info at a later date. NOBODY ELSE is allowed to make any sort of speculation about the murderer. Those who already did would better edit their posts, and do it now. I hope I made myself clear.
Geez, there is abusing people's patience, and then there's you guys...
