This of course gets a bit weird. I put in a short Penrose diagram of the Kerr-Newman black hole. Matter on the right I region will cross the r_+ horizon and fall into the III spacelike region. From there it must cross the interior horizon at r_-. Now there are two funny points here. The first is whether the r_- horizon is a mass inflation singularity and prevents any information from crossing. The other is a spatial surface in the cosmology region I has two alternatives that connect to two inner timelike regions IV and V. This illustrates some possible monodromy associated with the interior of a black hole. The prospect of this monodromy raises the question of whether these inner regions IV and V are in some ways entangled with quantum states in the exterior region. There then might be some physical region there instead of just this being a mathematical idealization. If so this interior region is filled with radiation and particles on closed timelike curves cycling around the singularity. The real question of course is whether there is some entanglement of states between the regions I and II, two timelike regions that may have multiverse considerations, and whether the ambiguity of how one pushes a spacelike surface forwards means there are also entanglements in the two interior regions.
