It's a fair question. It's also a safe choice that won't startle a young girl who is already on edge from recent events. Elidibus watches Kyoko as she takes the time to respond. It's clear he's listening to every word and perhaps all the nuance and hidden emotion the young teen imparts.

It gives him a hint that she is well aware of where the fault for her predicament lies.

"I see," Elidibus says, his brow furrowing in thought. "It's fortunate there was a means to cleanse your Soul Gem in time then. Yet we don't know what else may be required of us during this mission. Is the one who aided you now able to stay near you for the remainder?"

There's another reason the Ascian doesn't pursue more delicate matters. Being in proximity is enough for him to study the aether surrounding Kyoko; both her body and the item she calls a Soul Gem. His experience makes it easy to hold a basic conversation while also considering these matters from up close.
