Alex looked at Kai with strange eyes. The Kai he knew was not someone who would easily give away such an opportunity to praise himself. He always wanted to be the best, the first, and on top. So, it came as a surprise to both Alex and Wendy when the boy personally offered to go last, something must be going on in his mind.
Alex silently used the sound element to peek into Kai's thoughts.
His eyes glowed with a green light for a brief moment. He used 'mind read' on Kai without the latter realizing it. After all, he was not a mage yet, so he was not sensitive toward mind invasions.
Alex chuckled when he finally realized what Kai was thinking. The kid was so hilarious that he almost laughed uncontrollably. Well, that is his choice though, Alex would just have to go with the flow.
