INT. NYAX/OBI-WAN, ANAKIN, & SIRI'S CELL
Obi-Wan sits against the far wall of the cell away from Anakin and Siri, watching them as they sleep. A few days have passed since his experience in the torture chamber, and he is visibly worse for the wear.
With a yawn, Siri rises from her sleep. Sitting up, she notices Obi-Wan staring.
SIRI: Good morning, Obi-Wan.
OBI-WAN: Morning, Siri.
SIRI: (cocks an eyebrow) That's the most you've said in the past three days. I'm glad to see you coming around.
OBI-WAN: (absentminded) Coming around? I suppose I am.
With that, their brief conversation comes to an end; as Ben continues to stare at Anakin, Siri moves over to the corner of the room which serves as the cell's lavatory to relieve herself of last night's meagre meal.
Minutes pass, and finally Anakin awakens.
OBI-WAN: Anakin ...
ANAKIN: (looks up at Ben) Obi-Wan?
OBI-WAN: Come here.
Getting up, Nik walks over to Ben and crouches down beside the Jedi.
ANAKIN: What is it? Are you okay?
OBI-WAN: I'm alright, Anakin. Just listen to what I have to say.
ANAKIN: Okay. What is it you have to say?
OBI-WAN: You remember what I told you about the Force?
ANAKIN: Yeah. You said it's the "soul of the universe", that it binds everything in the universe together and gives those who can touch it amazing powers.
OBI-WAN: That wasn't the full story. (beat) My master taught me that the Force has two main sides -- a light side and a dark side. The light side is the positive side of the Force -- in harmony with love and life and peace. The dark side, on the other hand, is the negative side of the Force -- chaotic and in tune with fear, hatred, and death. (beat) My master also taught me that while the dark side is easier to follow than the light, it is not stronger.
ANAKIN: I'm following you.
OBI-WAN: After Qui-Gon died, I started to fear that Yoda might be wrong -- that the dark side actually is stronger than the light. (beat) I'm still afraid the dark side's stronger.
ANAKIN: There's an "and" or "but" somewhere in all this, I hope?
OBI-WAN: (cont'd) But I realized that I don't have to lie down and let the darkness roll over me. I can fight it -- even if I can't win, I can fight. (beat) I'm going to fight the dark side, Anakin, and I'm going to help you fight it, too.
ANAKIN: What do you mean?
OBI-WAN: Vizsla is going to do whatever it takes to twist you over to his way of thinking. I'm not going to let that happen. (beat) I'm going to use whatever remaining time we have on this ship together to prepare you for his assaults -- I'm going to teach you how to use the light side of the Force.
