The Clone Wars - S6E12 - "Destiny"

The fortune cookie is "Death is just the beginning."  Probably just coincidentally, this is similar to what Dooku says near the end of his duel with Yoda in Attack of the Clones:  "This is just the beginning" [2:09:49].

4:55 - Force Priestess (Serenity):  "We have been waiting for you, Master Yoda."  Vader greets Obi-Wan the same way in A New Hope:  "I've been waiting for you, Obi-Wan" [1:30:09].

Starting at 15:10 there's a musical cue of "Battle of the Heroes" from Revenge of the Sith.
