the Key (from Q drops) is the Map (the way things connect and the logical links between the components of the deep state apparatus)
the Stone (from Q drops) is the ability to act on the information

I've talked about "The Key" here a few times. This is merely what my information source calls it. There's been a lot of confusion as of late, I suppose largely stemming from the speculation I've injected unintentionally. I wanted you guys to know, though, that we as a group had already been told by Q what he means when he refers to the keystone, the key, or the stone. The first two lines explain that adequately.
