Yep, Morzone is right on the money. We do sign up and discussion in the same thread.

For those who are wondering (and so that they know this storyline actually does have some direction), what I'm doing with Jonathan is he is going to use Sloane's pen and markers and paper to track what foods and drinks turn people into what and what doors lead to what other rooms by writing on the walls, floor, and so on. This is going to lead to him trying to map out the entire Trick House Underground for everyone stuck inside it to know what doors can lead to what rooms, know where they're going, and what foods are "relatively" safe to eat. He's hoping this will lead to them figuring out every nook and cranny of the Underground and eventually find where a possible exit might be to help everyone escape...

...which is going to get the attention of the Trick Master in a bad way. By doing this, Jonathan's undermining the whole intention of having the Underground confusing, shocking, and bewildering, and that might lead to something bad happening (I haven't decided what, yet, but you're welcome to decide!).

Now, you're free to help Jonathan in this little mission once you learn of the plan from him directly (like how Sloane did) or see his work in action. You're also free (and highly encouraged) to interject your own ideas for having things change in the storyline, but even if you're stumped on that for now, trust me, things will take interesting turns anyway.
