I don’t like how the Resistance character Beamount played by Dominic Monaghan says cloning is a secret only the sith knows, would be cool if he said something referencing Kamino “Dark Science, Kamino…secrets only the sith knew” something along those lines, although some would argue the Sith are responsible for the creation of the clone army back in the prequel era.
We could source the audio from that iconic scene in Lord of the Rings when Merry and Pippin team up with Master Sifo-Dyas to defeat Count Dooku. (in disguise as Saruman)
