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 Lone Wanderer'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.
"Ha. Closer to reality than you might think. Listen, I was just as obnoxious at your age. I didn't take the G.O.A.T. seriously and look where I ended up. Just between you and me? The whole test is a joke. If you don't like the results, I can make your G.O.A.T. come out any way you want. Just let me know."
