The story continues in World 3, when the party returns to Tycoon. Bartz has picked up on Lenna's incredibly unsubtle crush, and isn't sure how to respond. This is used to explain his decision to leave with just Krile, and the plot progresses normally with Lenna staying behind in Tycoon and getting possessed by Melusine. Also Bartz and Krile chat about mortality, and how any of the remaining party members could die (hint, hint).
