Just what is he hiding?

In the beginning Alphie was glad to see John, but he was acting strange, it kind of scared her 

[John, calm down... John!] 

It was futile, John couldn't hear Zestari's voice, 

"now that I think about it... Rather than just paralysing your leg, wouldn't it be better to paralyse your whole body?" John asked as he raised his hand 

"No... Please, I'll stop, I'm sorry, I won't do anything bad anymore, Please!" 

[Tsk, he's losing control... And she told you not to recklessly use possession too...] 

"Ha... Now I understand why... That look of despair as you have all your hopes crushed, it really is the greatest feeling." John said with a grin 

"Stop!" 

John heard that word as two girls suddenly jumped at him 

"Hm? What's wrong? Ariel, Serena?" John asked as they laid on the ground 

There was no longer darkness clouding his eyes, it was back to it's normal green
