This is how Scotty concludes the conversation just before he leisurely pilots the travel pod around the Enterprise, by way of delivering Kirk to the ship. A minute previously he'd protested, "She needs more work, sir - a shakedown," etc. His tune changes as soon as he learns that Kirk and not Decker will be in command. In part because of the affirmative music behind the end of the conversation, the moment plays as if we are to believe he's not only sincere but certain that all will be well - which, of course, is far from the truth (transporter accident, engine imbalance, etc.). So is Scotty bullshitting Kirk (telling him what he wants to hear without necessarily believing it), or are the scriptwriters bullshitting the audience? Or both?
