Not to come to the Geniuses rescue or anything because I can't stand them. But they were trying various things. When they were walking around the building before finding the way down, they showed a couple of them just trying random things on the cryptex.
I can't STAND the Geniuses... I'm routing for either Air Force or the Southies... I'd actually like to see the Air Force take it tho. They're the only team that has consistantly stayed focused and stayed a team.
