Uh… two is better than one? I guess?
TestingOutTheTest suggested keeping the “lifeforce of your bond” thing in, which sounds just as handwavy as a Dyad without distracting us with proper nouns. If Palpatine was Snoke, then Snoke giving them a bond could be a long-game setup (in story payoff, not literal planning) for Palpatine to drink that bond up. Would just need to lessen/cut out Palp’s surprise when it happens, along with Kylo saying in the hangar that Palps doesn’t know.
How many times do I have to say this? Snoke and Palpatine aren’t the same individual; yes, Snoke listens to Palpatine, but it isn’t like he is some sort of VR avatar Palpatine controls.
