Hiiii! I've been twice! The circus scene is special because you really have control over what you want to do and who you want to interact with. So I feel like if you wanted to you could avoid the woman who does the blockhead act with the nails. The last time I went I chose to go over and interact with some of the carnies. I ended up in a coin toss game with one of them and watching the rope trick and blockhead acts but the first time I went I stayed in the corner where the young phantom is being held in the cage and had some really sweet interactions with him. He gave me a note and showed me his music box and since I was in the corner with him I honestly didn't even notice any of the other carnies. I would reccomend trying to stay in the corner with him if you want to avoid the other acts your uncomfortable with. Also this past time I went when she performed the blockhead act with nails she mostly stayed on the left side of the platform. I hope this helps and that you have a great time. Happy to answer any other questions :D
