Leonardo: We have had our first battle, Master Splinter! They were many, but we kicked... but we fought well. Splinter: Were you seen? Leonardo: Uh-uh. Splinter: In this, you must never lapse. Even those who would be our allies, would not understand. Our domain is the shadow; stray from it reluctantly, for when you do, you must strike hard and fade away, without a trace. Raphael: I lost a sai! Splinter: Then, it is gone. Raphael: But I can get it back! I can get it back... Splinter: Raphael!... Let it go.

Ha-ha. We have had our first battle, Master Splinter. They were many, but we kicked... [SPLINTER CLEARS THROAT] - We fought well. - Mm-hm. SPLINTER: Were you seen? - Mm-mm. In this you must never lapse. Even those who would be our allies would not understand. Our domain is the shadow. Stray from it reluctantly. For when you do... ...you must strike hard and fade away... ...without a trace. I lost a sai. - Then it is gone. - But I can get it back. I can. Raphael, let it go. [BOTH GRUNT] SPLINTER: Hey. [GRUNTS] Your ninja skills are reaching their peak. Only one truly important lesson remains, but must wait. I know it is hard for you here underground.
