Shouldn't Norman be malnourished *spoilers*
... and the house even more of a wreck?
There are times when we see "Norma" cooking breakfast for Norman after he wakes up and he leaves directly to do something.
I appreciated that the kitchen was trashed when Caleb went through it but, after this long, it should be much worse and the rest of the house should also be trashed.
There are times when he could be "Norma" and doing things to maintain the house and eat, however, sometimes Norman's life is too busy to allow that.
