Well, once he gets home from hospital and has the mansion modified for his disability, there will be a lot of adjusting.
He seemed to cope rattling around that big house when he was a child, but mainly by studying (and having Mystique for company). With no Mystique, Erik, Banshee or Havok, it will be a bit lonely in that mansion.
With the alternate timelines etc, it's hard to make sense of what's going on. I hope they have thought it through, because time travel tales are prone to plotholes and paradoxes.
Those metal walls in the picture look more like something Magneto would do, so maybe he is somehow involved with the school again after Charles goes off the rails.
