See, the first part of what Elidibus is saying makes total sense. The first part about him and Jingyi, he means. Of course their tension is understandable. Inigo can't blame Jingyi at all for getting mad at Elidibus, considering the circumstances..

.. and, well, Jingyi tends to get angry and fussy pretty easily anyway, so it's only a natural conclusion of something big happening.

But the second part is what surprises him. No, it outright confuses him. It's not even like he minds keeping it secret, it's just..

".. How would that impact your conversation?"

One could almost see the metaphorical confused question marks flying over Inigo's head here.
