Lol, just rotoscope Palpy’s face onto Finn’s. But honestly, Grandpa Sheev is the only one who was actually deformed by lightning. (That’s why it makes so much more sense in your Ep. III edit, Hal.)
I know! Someone removed the lightning from Palpster’s hands when he raises the Fleet, yes? Let’s just reinsert that lighting onto Rey. That’s how VFX work, right?
