Audio/visual unsynchronized: In the galley, just as Scotty exits, Spock orders: "Valeris, please inform Starfleet Command that our warp drive is inoperative." Yet Spock's lip movements seem to indicate that the name "Valeris" was dubbed over "Commander Uhura," which would make sense given that the latter is the ship's communications officer and she is standing right there, but was likely changed to match the subsequent dialogue and action: Valeris asks, "A lie?"; Spock replies, "An error"; then Valeris walks away as Spock continues to speak with Uhura.
