If she had been in his place, she would have definitely kept the Elder wand for herself. After all, Harry did deserve its ownership after taking down the greatest dark mage of all time.
Zach had expected a debate of this magnitude already. Therefore, he had been waiting for a good occasion like this to end the story so as to avoid attracting the unending questions of the audience. He hoped that they would discuss it with each other instead of chasing him down the street to find out what happened after.
Although there were still some people who didn't understand what 'no questions' meant. But Zach didn't turn down anyone who raised their hands to ask a question.
