Luke: How can I be one of these Jedi? I've never even heard of them before.
Obi-Wan: Your true father was a powerful Jedi, a strong user of the Force.
Luke: The Force?
[SFX]: whooom
Obi-Wan: The Force is what gives a Jedi his power. It surrounds us and penetrates us. It binds the Galaxy together.
Obi-Wan: It's an energy field created by midi-chlorians - microscopic organisms that exist in all living cells.
Obi-Wan: Your father had... an unusual concentration in his blood. Blood which now flows in your veins.
Obi-Wan: To those who hunt down the Jedi you are already a target. You always have been. Thus the need to keep you hidden.
Luke: But trust me, I didn't do anything! I don't even know any of this stuff.
Obi-Wan: Jedi are normally trained from birth. I can help you to hone your skills.
Luke: But I'm... 19 years old. Will starting the training so late be a problem?
Obi-Wan: Uhh... no, not at all.
