Kell is moving a lot, so I think it will be good for her to see glimpses of the cavern they are kept for the first week. The general area of the pit, the stomach pods where the Summoned are put when they arrive, the only water source they have, some glimpses of monsters and the weird shrines. His vision might be a bit blurry at times because he has a pretty major head injury (that he's not admitting to anyone about).
