Inigo is wondering exactly where along the line that happened too. Because he felt like he was at least starting to get a semi-decent grasp on Zetta. The whole conquering thing, sure. The getting a body back thing, sure. He seems to want to be the overlord of some place, Inigo understands that all.

But did the guy just imply he'd help all of them?

"You were planning on sending everyone home?" This isn't as comical of a surprise as Inigo's usual surprise at Zetta's.. Zetta-ness, but it's surprise all the same.
