I have been doing the same, Anon. I sometimes ask you guys for prayers during tough times and it felt great knowing there are complete strangers out there who wouldn't hesitate to do so at your request. If this timeline has taught me anything it's that there were people out there praying for someone to save us, and God answered with POTUS. The signs of great evil is not only out there, but it's thrown in your face sometimes in a daily basis, whether it's a symbol, a statue, etc, they flaunt their evil openly. So, pray, because it's one way to fight back. We have God backing us up.
It was actually in The Dark Knight, and the name bats gave it was "SONAR".
POTUS is Batman giving Lucius Fox (Q) the authorization to use the keystone (SONAR) to defeat the joker (DS)
In the end, Lucius decides to destroy the technology because it wasn't inherently good to begin with, it's eerily similar to what's happening right now.
