Master Yoda: Such darkness. Such evil. When will this happen?

Qui-Gon Jinn: It is happening right now. It has always been happening. With each day the Clone War wages, evil is growing in its power. What you felt in the cave is merely a portion of what the dark side now holds.

Master Yoda: Such power. Any hope that the Jedi can prevail, is there?

Qui-Gon Jinn: There is always hope, my friend.
