Nothing's really popping off in Twilight Town. There's no objective of note established here either, like a factory or something. Only thing happening here was developing Ryoko's relationship with the Mayor, showing that even people affiliated with the Empire aren't liking what the 'General's', or at least one of them, are doing over and over, and making her take more intelligent initiative. If you had other business for being there that doesn't really pertain to business and just some form of pleasure, i.e. character development/interactions not pressured by rebel activity, then do your thing.
But I'll take the time to say this now: For any of the Empire intending to make surprise trips to TT, your power is limited. The sect of Imperial forces there are loyal to the Mayor and have worked with him for quite some time. They'll respect people in positions of power within the Empire, but won't do anything rash for you. No oppression, no intimidation, no violent acts. If anything there is no place they'd rather be stationed. It's essentially just an 'unwind' and 'interact' world, nothing huge for now.
And do not summon Heartless, Nobodies, anything that starts a panic the minute anyone sees it. Otherwise, your three strikes are already used and the consequences of it come, and are likely to be permanent.
tl;dr - Respect his authoritah.
