We would really like to heal and prepare outdoors, rather than indoors.
   One of the ongoing issues is the sensitization associated with mind
   control.  Every minor discomfort becomes intense because acting on it
   can be a way to control us.
   Karl's favorite animal is the mosquito.  He watched them as a child,
   let them feed off him, many others have seen Karl covered in
   mosquitoes, happy.
   Now Karl experiencing great discomfort when mosquitos and other biting
   insects eat of him.  We infer that he used to use willpower to
   reinterpret the slight pain and irritation as pleasant care and
   connection with insects he appreciated.  But now mc acts when he tries
   to use willpower to change his experiences.
