Hi guys! I think that Jack will be the most helpful because he is a "mechanic". He is the person that I think would be the most probable to disable the machine. Because he knows mechanism stuff because he has an Uncle who is a mechanic. Izadora's mind is in a blurr so I don't think that she will be much use to the characters right now. The adults are with Xaafuun right now , so I doubt that they will be much help. Except of course for distracting, but that would be after all of this time changing stops. I don't believe that Grady will be of much help. If anything, he would probably tell a Skreep that the others left if one came in the cell and asked where the others were. So, I think that Jack is the best choice for this question.
