So close! The commas are in the correct places and everything. If only the writer had avoided the dreaded arbitrary capitalization… *scary music*
“Yes, sir, we were able to resurrect your wife, but there’s a… problem.”
Usually, I see writers fail to capitalize the first word of a new sentence following an ellipse. Here, the ellipse is within a sentence, and the word after it should not be capitalized.
Maybe the writer of the original wanted to place special emphasis on the word problem, in which case italics would be the correct choice, not capitalization. (Capitalizing only the first letter is worse than using all caps; readers will at least understand what you’re if you capitalize the whole word.)
