Unfortunately, most of us do not have the luxury of immortality. Josiah is a valued member of the Refugees. He's an asset. It is an inconvenience to have him in his current state, and if you are not going to tell us why you need him like this, then I at least ask you to restore those memories within a reasonably short amount of time. You owe us more than that, but I don't expect to get much cooperation from you.
