In case there’s any lingering ambiguity from the trailer (and McDiarmid’s appearance at the panel!), I can 100% confirm that Palpatine is back in The Rise Of Skywalker as I just asked JJ. He’s thrilled - and slightly incredulous- that McDiarmid’s presence on set didn’t leak. pic.twitter.com/qDzPQagXSW
