Star Wars: Misc.
There are at least four references to the original Star Wars trilogy in this episode.
1. Ronan (to Bra'tac): You are weak, old man!
This is very similar to the Darth Vader/Obi-Wan Kenobi fight in A New Hope, where Darth Vader says "Your powers are weak, old man!"
2. The battle over Antarctica is very similar in visual style to the battle of Hoth in The Empire Strikes Back.
3. Our hero is frozen in stasis at the end of the show as his beloved looks on, very similar to the end of The Empire Strikes Back.
4. Sam starts to say something about her true feelings and Jack says, "I know," similar to what Han Solo says to Leia at the end of The Empire Strikes Back.
