Mister Brotch inherited the position of schoolteacher from his father and grandfather. Since the day the Vault 101 residents entered the vault, there has been a Brotch as a schoolteacher. Mr. Brotch is concerned about carrying on that tradition, but with no children of his own, he is beginning to worry that he will be the last in line. He is the man responsible for administering the G.O.A.T. exams.
In the player's youth, Edwin can be found in the classroom. During the Trouble on the Homefront quest, he can be found in the Vault 101 cell. If he is released, he will join the rebels in the vault's clinic.
