End of Time Party Lines
It seems several unique "take me along?" lines existed for the parts of the game where Crono was required to be in the party:
Actually, these lines appear when you talk to Crono in the End of Time.
I feel like elaborating on this comment of mine from years ago.
As you probably already know, in the final, you get a prompt instead of dialogue when you talk to Crono in the End of Time, since he's a silent protagonist. The pre-release doesn't do that. Instead, it flips the role of party leader and reserve member: The
party leader asks Crono to join them, and the player gets to choose how
Crono responds. That's what those lines are for. So they're for when Crono is out of the party, not the pre-Ocean Palace when he's always in it.
It's too bad it doesn't work well with how the final behaves when making decisions. It'd look strange if an active PC asks a question yet they're the one thinking over the question.
