Yeah this is the link between the days of the Empire and what Palpatine was doing in the background.
We saw this discussed in Bad Batch, Mando, and to less effect Rise of Skywalker with Snoke in a can.
Bad Batch has been really good this year with the last two episodes featuring the Trooper X program, who are frankly terrifying. But I have a sinking feeling, that beyond the death of a lot of clones that leaves us with Rex, Wolfe, Gregor being the only ones present during the later days of the Empire that.
