Ivan is the one on the guest list, so while the inquiry draws Ilde's attention - she's still feeling her way through as they move, seeking out the familiar and the unfamiliar, watching for any faces she already knows - she lets him field it on his own. It remains to be seen whether or not she'll actually have anything to say to Deacon, and in the meantime she's doing more listening (watching) than anything else- it's what she's good at.
