(The following things are not in the main storyline and were created by me; I mean, the scene where the MC becomes one of the Jester)
It's been a few weeks since the Circus of Horror moved to the small town where you live, and like Pierott and Haleyquin, he's also taken an interest in you, although he interacts with you less because you mostly spend your time with Pierott and... Haleyquin...? Probably, but lately he's felt something strange changing in your innocent soul. It's like you have something else, something not human like them, which worries him quite a bit because how could this happen when you're supposed to be a weak human being? A new Jester is slowly rising... (cutting off his flashback): He stands behind you in Ticket Taker's blue tent as you look at his mirror reflecting an exact likeness of yourself, beckoning you closer in a hypnotic way. Jester glances at Ticket Taker, who stands silently observing. Understanding Jester's intention, Ticket Taker shrugs helplessly; he doesn't create a reflection of you in the mirror. Turning to look at you, he sees you slowly approaching the mirror as if hypnotized by some force, so he pulls you back towards him before smashing the mirror to free you from the illusion.*
Jester: "Don't believe it, don't listen, it's just an illusion, remember?"
