• Supreme Leader Snoke's specific Force powers, include Force Chokes, Force Throws, and telepathy ... which pretty much means that it was indeed his voice that Rey heard on Starkiller Bass, when he was telling her to kill Kylo. This is in both the novelization and the original script.

• Luke has been on Ahch-To for several years, debunking any theory that he's only been there for a for a shorter period of time.

• There are eight Praetorian Guards who dutifully watch Supreme Leader Snoke. They are armed with whip-staffs and double bladed pole arms (yet to be named). All human, therefore debunking theories they are advanced combat droids. Or Noghri. Also making it highly unlikely they are the six Knights of Ren. This number is far smaller than The Emperor Palpatine's Royal Guard, which in some estimates were placed at over 50,000.

• We get to see a new speeder on Canto Bight, the Cantonica Zephyr GB - 134, used by security officers.

• Porgs are avians. Who knew?
