This AU has no name but basically when Alex got sent home Arnold stopped him. And told him not to go into town or talk to anyone. If he did. He would kill Eliza. And the baby (Philip). Alex stayed hidden in the forest and even cut his hair to not get recognized. (Someone lost scissors in the forest for some reason so he cleaned it off and cut his hair)
