More it's that a Stand being so integrated into herself makes expression rather meaningless and worthless for the most part. Conversation isn't needed, movement isn't needed, they both just sort of know what's going on without anything needing to actually be communicated. It's a while weird situation she's not too familiar with at the end of the day.

Jolyne's merely shrugging a bit in turn, she's... sort of seen the one picture he's talking about in her trying to figure out any shit about the family. And Jonathan being the only one in any sort of book she'd been looking through. "Kinda explained why that dickhead was built like a fucking mountain and just as tall." She means her dad, of course, but like hell if she wants to use his name or that title right about now.

For the Dio situation she's going quiet and leaning back without really thinking much of it. This is more a conversation for the two of them than herself as she's no help anymore on that topic.
