[@Yankee] Well, Phil did just partially manifest his Stand in a public place. Subtly, or as subtly as is plausible given what his Stand is, but somebody paying attention to everyone around them might make note of it. Alternatively, they might notice that there's a famous skateboarding pro wandering around in a mall in Italy, and want to say hi to them and their shopping-obsessed friend. Or both! So there's a thought for you.
