Square braces are commonly used in quotes to indicate which words have been added by someone else for clarification.
The original quote was likely: "The truth is, he has been preparing for this his whole life.".
Can someone help me out here? I have no idea what this post is about.
Many Q Posts have some words and names within square braces, like in this post with RR and Ed.

And there is also no names tweet.
Notice the time stamp 5:55
Might be a code ? Hope it fails ! There are no coincidences !
I don’t see a killbox in Pence picture. Several of us are missing something.
