What does Johnny’s hand look like now? What does this mean for his apprenticeship? From chapters 1-2

Johnny’s hand is horribly burned. Although the local midwife, Gran’ Hopper, does the best she can to treat it, she forgets to keep the hand flat and instead allows it to turn in on itself. Because of this, he loses the use of his thumb and is permanently crippled. Johnny will never be a silversmith.
