Meeting again after a long absence
Because I think we won't see the gang, just the fire siblings' plans, and a reunion between Ty lee, Mai and Zuko, I mean, I think they were better friends with Zuko than Azula, but secretly, cause as an spoiled brat she is, she'll jet jaleous, or because they joined her just for help Zuko secretly and betray Azula, I think that for that think "X is calling me to do that/ to join Azula. or x it's giving me strong hints" but he just didn't reminded that in Zuko Alone, of his friends??because he was remembering his family's troubles. I even think after Ursa's desaparition, (as royalty marriages are almost always arranged, and since Ozai entrusted Omashu to Mai's father,) that Mai is Zuko's fiance (or at least was, ??until the banishment). I mean that would be impacting, and by saying it, I don't mean they must be in love, just as good friends, or even just as very polite known people.
Or it could be named : Confussion /Missunderstood (for Zuko, I mean yay, I'm Zutarian, but this is Fire Book! and Zuko's the main FN character!)
