The Rover's Return

I've said this before, and no one seems to listen; but I'm going to say it again.

If you're referring to a fictional person, or other entity, I wish you'd say so.

I don't imagine anyone would call this particular question a difficult one, so you can probably get away with it in this instance. But the principle still stands; if the contestant was having to think about this at all, it would be a big help to know that they needed to think of of something that doesn't exist in the real world.
