I'm pretty impressed with how Araki is writing Lulu and Bobby Jean. The way Lulu is stressed about her Stand not working, but avoids talking about what's actually making her upset and throws seemingly unrelated tantrums instead, really does feel like how a lot of kids would act. I also like how you can tell Bobby Jean is used to dealing with it, lets her get her outburst out of her system, then just coaxes her into telling him what's really wrong. They're a fun little villain duo.
