Sisters Charity, Cera, and Clara have looked after Bill since he was abandoned on the orphanage’s cracked doorstep in a large birdcage. The Nuns have provided the foundation for Bill’s moral compass, much like Yoda or Mister Miyagis. After countless parents frightened off by Bill’s DRD, The Nuns prayed for an understanding adopter to come along. Something must have been lost in translation, because Tim’s the closest thing Bill has to a guardian. The only reason they’ve let Tim and Bill set up shop in the basement is because it adds a few more dollars to the donation basket every week. Ageless.
