1:42 - Son (to Anakin): "Join me, and together we can change the balance of the universe, my friend." Twice in The Empire Strikes Back, Vader says similar things to Luke: "Join me, and I will complete your training" [1:50:39] and "Join me, and together we can rule the galaxy as father and son" [1:51:45], and in Attack of the Clones, Count Dooku says something similar to Obi-Wan: "You must join me, Obi-Wan, and together we will destroy the Sith!" [1:33:06].
3:03 - Obi-Wan (to Anakin): What in the blazes are you talking about?" He uses this same expression in Attack of the Clones: "What in the blazes is he [Anakin] doing there [on Tatooine]?" [1:22:27].
6:56 - Obi-Wan: "Anakin: always on the move." He uses this same expression to describe Anakin in Revenge of the Sith too: "Always on the move" [10:01].
8:02 - Father: "I am not dead yet." This seems to be a reference to what Obi-Wan says of himself in A New Hope: "Oh, he's not dead, not yet" [31:24].
8:12 - Son (to the Father): "I hate you!" Vader also says this to Obi-Wan near the end of Revenge of the Sith [2:00:15].
13:07 - Son: "I have done what is right or what is wrong, depending on your point of view." This seems to be a reference to either Anakin's "From my point of view, the Jedi are evil" in Revenge of the Sith [1:58:33] or Obi-Wan's "from a certain point of view" in Return of the Jedi [46:23].
18:23 - Anakin screams "No!" after Ahsoka falls. In terms of masters and apprentices, this is something of the opposite of situations in The Phantom Menace, where Obi-Wan screams "No!" after Qui-Gon is struck down [1:59:48], and in A New Hope, where Luke screams "No!" after Obi-Wan is struck down [1:32:24]. In different circumstances, Vader also screams "No!" in Revenge of the Sith [2:08:43], and Luke does so in The Empire Strikes Back [1:51:30].
