The image on the prime Jedi seal apparently resembles snoke. Thus implying that he may be the prime Jedi who is composed of light and dark sides. This was surmised by reddutirs and isn't explicitly stated in the dictionary. Like many of us in theRPF, Luke is a hoarder of Jedi paraphernalia. His compass is from the emperors old observatories. Leia is in a coma after being exposed to space after her ships bridge is compromised from a first order attack. However it wasn't Kylo who shot, but his wingmate. Luke and Leia wear matching homing beacon bracelets. Kylo has a secret plan to enhance his status / power that snoke isn't aware of. The knights of Ren are absent from the dictionary. Ren and Rey have a force bond but go their separate ways at the end of the movie. DJ stands for "don't join." Poe wears his mother's ring on a necklace and this ring is meant for the right partner. Leia demotes Poe for insubordination of holdo's command. Poe isn't inspired by holdo which triggers his insubordination. Apparently Poe had sent rose and Finn to thwart the first orders hyperspace tracker, which can track a vehicle even if it has gone through hyperspace. Phasma's armor is made from one of the emperors old ships.
Also, if Luke has a lightsaber, it isn't included in the dictionary. Although he has green milk and eats some odd looking fish.
