Zoe smiled, "thanks for your concern guys, but I'm fine.  Using my ability takes up energy, so the more I use it, the more tired I get.  I've already used it three times in here, once to make sure I still could do it, a second time to deal with a nasty trap, and the third time to demonstrate to you guys what I could do.  I'm just not used to using it so much. However, I do have an idea on how to help you find your friend.  See these walls here," she said as she approached on of them.  "They're kinda hard to miss.  Well, they're only about ten feet tall right?  There are three of us.  Perhaps we can help a scout get on top of the wall and scout out the maze, or determine where the others are.  Of course, there's no telling what might happen, so this might be a bad idea.  Anyway, what do you two think?"
