Since there aren't many tangible things to guess where they might take the Season finale I thought it might be fun to share a new inside joke I found smuggled into their set design:

The original FBI logo looks like this:

The initials of their Motto "Fidelity, Bravery, Integrity" again add up to FBI.

In the show they use a slightly different logo:

The initial of their Motto "Valor, Heroism, Service" add up to VHS, which is the video standard that was most common before the DVD-Player came along.
