If you look at the drop from the 19th, Q talks about who signed the FISA and tells us to go to pgs 380, 390, 391, etc. Those signatures are Strzok, McCabe, Rosenstein, and Lynch. Then he talks about Firewalls. These are the FIREWALLS.
I think based on that drop, the FIREWALLS were a failsafe to stop the Trump presidency, in case the unthinkable happened and SHE lost. Therefore, the FISA plan was the LP / PS "plan" that was discussed. those 4 signers were the last defense- the FIREWALL.
