The third point of view:
Everything happened too quickly for him to comprehend. After Julie bumped into whatever that was, he turned around screaming instinctively. However, a huge frown crossed his countenance when he discovered what had startled him.
It was no other than Isabella's mischievous brother Neon and he was still screaming even after he - Julie - had stopped. It must have been his hair - Julie had screamed in fright because he felt something bristle touch him in the first place. Obviously, he was all scared for nothing.
But then his eyes widened, "Oh no," That scream combined with Neon was enough to wake the whole household - and the street as well.
As if someone said "Jack Robinson" the hallway bulbs lit up immediately and illuminated the environment while blinding him momentarily. Light switches began to be turned on one after the other in each room and panic set in.
