...Scurvy?
I'm just thinking of the logistics of pretty much everything disappearing and the last tree dying...
Do you think Simon had scurvy? Well... Everyone really, but still.
There is an astronomically small chance that the survivors are getting fresh fruit and vegetables every day. Add onto that fact that Simon was a convicted criminal and would not get the same quality of care as the average citizen.
So... Scurvy.
Also, fun fact, one of the symptoms for scurvy can include irritability!
