In truth, Cas and Tastro have no way of knowing if their current state of being is final. There’s the chance that one day, they could suddenly lose their consciousness and become just another pair of mindless monsters. Slaves to their instincts, unable to control themselves. No longer truly people. This thought terrifies Cas, and he hides the possibility of it from Tastro as much as he can. As to how Cas knows about the possibility? That’s a secret he’ll take to his grave. Or mindless regression. Whichever comes first.
