Jacob, Marco, Ryan and Ava sat in the small examination room, their faces pale and their eyes wide with fear. The room was cold, and the walls were bare, with only the occasional piece of medical equipment to break up the monotony.

Ava, the youngest of the group, looked particularly frightened. She was clutching her teddy bear tightly, as if it could protect her from the horrors of the hospital. Marco, who was a few years older, was trying to put on a brave face, but it was clear that he was just as scared as the rest of them.
