Cassandra is here largely because Akane is here; she doesn't really get the point of anything that's going on. She's not sure if this sort of thing is normal for humans or if it's just another thing that makes this world so strange; she doesn't really have the experience to judge.

She watches the ballet for a bit (it's lost on her), then watches people attempt to ride the Bouffalant that doesn't want to be ridden (also lost on her), then makes her way over to the site of the race (also lost on her, but Akane's competing and she wants to be supportive). At some point, she might drift over to the egg stand, but she thinks that might not be a good idea: she might end up with an egg that way.

As usual, she's accompanied by Blade the Silvally and (now) Lythie the Murkrow, the former brightly sparkling in the sunlight while the latter perches on Blade's head (and Cassandra is not sure where Lythie got those sunglasses and isn't sure she wants to know). Blade seems at least as nonplussed as Cassandra about this whole thing, while Lythie is... possibly looking for trouble to get into. Cassandra's not sure, and she's honestly kind of worried.
