There's a lot of the major I to borrowed VI when she's outside (C to Ab and then F to Db after Jacen gives some exposition) and then the part I think you're talking about is when it plays a version of Ahsoka's theme when they're flying into the whale's mouth. The part I think you're talking about is when they fly into the whale's mouth and I think that's Ahsoka's theme but I could be wrong.

@@mrvoltar yes that part. it comes immediately after Sabine's theme in the credits with Ahsoka's theme jumping in a few measures later. but in episode 5 it seems to be going without her theme overlaying it like it does in the credits. but then again i could totally be off. I know the official kiner title for it is "the hyperspace jump" from volume 2. it has that really big majestic building up sound.
