I have a hard time imagining Kimmet will give Michael orders to leave Ft. Irwin. It seems Kimmet sees Michael as a valuable asset and wouldn't want to put him in a dangerous situation. If Michael leaves the fort my guess is that he'll do so by either blackmailing Kimmet to allow it or by just disobeying orders.

As has been suggested in other threads I think we'll hear part of Michael's info dump on Kimmet, including what happened to Michael at the Water Works, but that will probably happen in the chapter finale.

As a whole, I think Chapter 30 will focus mostly on Saul/Victor/CJ and The Mallers/Burt/Lizzie/??.
