Sentimental Star Journey
As the trio leaves Wonderland, Sora reflects upon his journey thus far. Despite going to a different world, he has still yet to find the King, Riku, or Kairi. Donald and Goofy notice Sora's depressed demeanor and encourage him to keep searching.
Meanwhile, back in Traverse Town, Yuffie is just leaving Cid's shop when she runs into Sora, Donald, and Goofy. Sora explains they came back to talk to Leon about a few things. Yuffie directs them to the basement, saying Leon is currently there training. The group head to the waterway, finding Leon. He greets them with "you've found the Keyhole...".
