Romulan Commander : "You must have your own ship."TOS : The Enterprise Incident
Spock : "Commander, shall we speak plainly? It is you who desperately need a ship. You want the Enterprise."
Romulan Commander : "Of course. It would be a great achievement for me to bring home the Enterprise intact. It would broaden the scope of my powers greatly. It would be the achievement of a lifetime. And it would open equal opportunities for you."
