Honestly? Casey's excited. She hasn't been to a party, let alone a costume party, in longer than she cares to remember.
Bouncing around the multiverse and never really staying anywhere long enough to settle in all the way meant that she was constantly on her guard. Here, she probably still should be, but this is the calmest place in a long time and she's going to take advantage of it. Besides, how can she not be excited when she has actual fans for the first time in her life? For the first time in her life, nobody asks her questions about her dad. It makes her feel a little guilty, but mostly she's just kind of enjoying being appreciated in her own rite.

Because she'd volunteered for photo oops, Casey was careful when she picked out her costume. She wanted to make sure that it was within the theme of the event, pretty, flattering, but also kid-friendly, just in case this was supposed to be a family-type event. She doubted it, but one never knew and if she was going to be taking pictures, she wanted to look good but also appropriate. So, she found a cool set of fabric wings and set about cobbling together the rest of a butterfly costume.

Throughout the night, she tries to mingle with locals and other Supers alike. She might have a few drinks, but they don't really affect her anyway.
She tries to keep herself approachable via open body language and a smile. Casey plans to make the best of this and really enjoy it, just in case everything goes to crap sooner than later, like everywhere else.

The next morning, Casey spends the better part of the parade in the air just sort of getting the best look at the area down below so that she can ensure it's safe for everyone. Even though this isn't her permanent home, it feels like her responsibility to keep it safe, just like it always feels like it's her responsibility to keep places safe when she's living in them. When someone has powers like hers, it's hard not to feel that way.

At some point when things look like they're going pretty smoothly, Casey will float back down to the street and take off and tuck away her cape so that she can enjoy the second half of the parade on the street with everyone else.

(( Casey will definitely be at the film festival for at least part of the afternoon and evening. If you want to do a thing with her at this event, absolutely hit this back with a start! ))
