When Thi-Sen gives Kenobi the big hug, the other Talz in the background are silently laughing.

Chairman Cho makes reference to "The Convention of Civilized Systems," the first such identification of this specific bill of rights in Star Wars storytelling.

C-3PO refers to Thi-Sen as "Son of Suns," another artifact from old Star Wars scripts. Old drafts made reference to a prophesized hero being named "The Son of Suns," but it never made it into any of the movies. Some Star Wars fans think the Skywalker / Chosen One prophecy might make mention of "Son of Suns," but its casual use in Thi-Sen's title suggests that's not the case. Also, some fans mistakenly believe that the crowds during the Coruscant or Naboo celebrations in the movies shout out "the son of suns," but this was debunked in 2007.

The Pantorans are either very light or Rex is quite strong.

Anakin's dialogue when he calls Chuchi "most impressive" echoes a statement Darth Vader makes about Luke Skywalker in The Empire Strikes Back.

The totem poles in the Talz village are carved of ice. Their huts are made of animal skin stretched over bones.

Given that the Freeco bikes only hold one passenger / pilot, C-3PO drives his own speeder. In the original script to the first Star Wars movie, Threepio once made reference to piloting speeders being one of his "30 secondary functions."

The designs of the cold weather clones draws generously from early The Empire Strikes Back concept and costume art by Ralph McQuarrie, Joe Johnston and John Mollo.
