In Baedal - especially with someone she remembers from the Vault - she doesn't make any assumptions in either direction. Maybe he doesn't react because it doesn't bother him; she's tired of being treated as though existing is something she does expressly to disturb other people. As though she's inherently a provocation.

(Ignorance is more likely, even in Baedal, but-- it'd be nice not to be looked at that way, and there's no one around to care if she pretends.)

"That's why I was there." In the Ctenophora, specifically, and she means because she's got a friend there and not because she's inclined to creep on Bruce; she'd probably have investigated the Vault sooner or later either way, but Hasi's presence tipped it.
