I agree with Poppa

The radio should be the more “blatant” reveal or hint. Just pepper things a bit though out the movie.

Also, in regards to Hal’s TFA:R, he is adding a few Palp things, sound clips/music wise, but not out right reveal things.

With a combination of these two things, there is some hinting that should progressively reveal things. But not out right reveal it. All of us can agree the who Palpatine treatment from TROS was just BAM! Right in your face and even in the crawl.

Let’s just keep hinting at it for the time being.
