In Harry Potter and the Chamber of Secrets (2002) Extended, Tom Riddle says to Harry Potter about diary:

Tom Riddle: Still, the power of the diary began to scare her. She tried to dispose of it in the girls' bathroom. And then who should find it but you?

Why question mark kept after "you" instead of after "it"?

Why not like this:

And then who should find it? You Harry?

    Why would you think the question mark should stay after "it"? The question mark always goes at the end of the sentence.

Here is some dialogue that illustrates its use:

"We were sitting in the pub talking about our boss when who should walk in but our boss!"
