McAiken did get Nadia's attention from some seconds, as he went about the shield. Indeed, she knew of that. She mentally pffed - object, pet, friends... seemed whatever could be used as shield, didn't it?

Nadia raised her eyes to the desk and walked to take a rock herself, then did a double-take and used her plain-hat to put a group of stones, and walked around the class giving them out to the various students around who looked like didn't want to get off the comfortable chairs. Not that Nadia could blame them. But there was a certain disatisfaction she felt when, a.) she was standing motionless for too long, hence she had to move at every given oportunity, and b.) she class was delayed in every silly way.

So she helped them to the rocks, in only to move faster, though that, in her motions, she didn't show.
