Well, it's something you'd expect. After all, Wellstone is a prestigious school, so checking on the students that register is normal. The thing is, what kind of deal was made to let him play Cripple? Or was it that "Playing Cripple" was somewhat the condition for John to be admitted into school again? Taking into account that John has the power to throw into caos the current state of balance established by the ones currently in power.
Somewhat it's hard to believe that with Seraphina back, john is going to chill out a bit and with the warning to the king, the bullying will be back to the usual. Things are happening and change is coming.
As for the nurse, I think that's just part of his personality.
Well, it's hard to imagine that the school files Isen hacked into were unavailable to the faculty. But from what John has already said it seems more to me that he WANTED to play the cripple than anything else...?
John might have wanted it, but the thing is why the school LET him do it. Being John a dangerous individual to them and with the precedent of him going haywire at his previous school, that decision wasn't as simple as it might seem. Even John's father might have something to do with that. We don't know.
We'll figure some more after the principal get the gist of what John has been doing. He actually might be penalized or even expelled if there was an agreement of him playing cripple.
I have even more respect to the nurse who knew how powerful John was all along and still used to stand up to John and stop him from leaving.
I wonder how long it'll be before everyone starts putting two and two together when they notice Arlo, Elaina, Ventus and Meili avoiding John. (Four of the strongest kids in school can't even look the "cripple" in the eye? Lol. Maybe even Isen can't look John in the eye either.)
