AND...
Yes, there are cameras in the house, because the young one has a blood clotting illness (Hemoophilia) and the older one was worried about accidents, seeing how they happened in the earlier years. As consequence, yes, he caught the young one in other kinds of situations...
Part of him wants the cameras cos he is worried, and part of him is getting to develop curiosity about the other's actions and... his own feelings...
Peeing Tom syndrome is basically what we ALL READERS DO ^_^ hehehehe
