Herminny knew she had to do something watching their beachball number deplete but none of the beach balls had come near her or within her reach without trampling someone till now. she saw one red beach ball heading right to the danger zone and having her wand at the ready, "contego red beach ball", putting as much concentration into it that she could musster and saw the beach ball knocked way out of the way of the danger zone but there were still a couple left. She had to be vigilant but for now she had done her job.
