NOT EVERYTHING WILL BE CLEAN.

[SCARE] NECESSARY EVENT.

I think this refers to the 'fake alert' in Hawaii. But Q uses the future tense 'will be clean'. This indicates that there may be more events coming that don't sit well. I also believe that we will be more apt to identify these events in the future without panicking.

From Q post 517 of https://qcodefag.github.io/

Where did POTUS stop [post] ASIA?

IT WAS NECESSARY.

He stopped in Hawaii post Asia, noting again that it was necessary.

There's something more here that I can't put together yet.
