Diana was a fast girl. She was also very good at turning up at places unnoticed, and that's exactly what she did at the basement. Without a doubt, the adults would arrive within a few minutes and start ruining the scene. 

Someone had without a doubt got hurt. That was no scream of surprise or excitement, it was pain, and the legitimate real kind. It wasn't a paper cut. That girl must've been really hurt. And a look at the small pool of blood in the basement confirmed any doubt she may have had about violence. Taking a look around the room and memorizing it down to the smallest detail, she turned to leave. This was enough for now. Moving as stealthily as possible, she made her way through the halls to the nurses office, albeit the long way. 

She didn't intend to arrive just yet. Time needed to be given before her side of things were relevant.
