VADER: You are beaten. It is useless to resist. Don't let yourself be destroyed as Obi-Wan did.
VADER: There is no escape. Don't make me destroy you. You do not yet realize your importance. You have only begun to discover you power. Join me and I will complete your training. With our combined strength, we can end this destructive conflict and bring order to the galaxy.
LUKE: I'll never join you!
