9:43 - C-3PO - "I have a very bad feeling about this."
15:08 - Senator Farr: "He is our only hope." Leia uses the phrase "only hope" twice in A New Hope ("Help me, Obi-Wan Kenobi; you're my only hope" [35:35] and "You must use the information in this R2 unit to help plan the attack; it's our only hope" [1:38:49]); C-3PO uses it once in The Empire Strikes Back ("Your highness, we must take this last transport; it's our only hope" [31:49]); Obi-Wan uses it once, referring to Luke, in Return of the Jedi ("You were our only hope" [47:24]); and Luke uses it once, referring to Leia, in Return of the Jedi ("If I don't make it back, you're the only hope for the Alliance" [1:19:39]). Sio Bibble also uses it in The Phantom Menace: "Our only hope is for the senate to side with us" [23:48].
18:40 - C-3PO: "I am a protocol droid on a diplomatic-." 3PO is interrupted by Nute Gunray, but it seems that he was about to say "on a diplomatic mission." This phrase appears at least twice in A New Hope: Captain Antilles tells Vader that "We're on a diplomatic mission" [5.55], and later Leia tells him, "I'm a member of the Imperial Senate on a diplomatic mission to Alderaan" [7:58]. Near the beginning of her conversation with Vader, Leia is similarly interrupted when she says, "When they hear you've attacked a diplomatic-" [7:43].
