Wells tried to push his way ahead of the crowd. He didn't know how to show off the fact that he could survive being in the ozone layer, as it was so far away. And he couldn't shout the truth to them. If he jumped above the heads of everyone there, he might hit someone in the head. After a few minutes of pushing through people, he decided to jump anyway. The roof was barely tall enough, and the sight of someone leaping above a crowd of "avatars" made it obvious that said person was, indeed, an avatar. The way that he shouted in mid air made it even more obvious. But above all else, it was obvious to the person he landed on, who certainly looked like a "Diancie".
