[Exorcist, All Allen] A Beginning at the End

After watching Exorcism, I thought there was so much bromance, so I couldn't help starting another story. Like before, the characters might be out of character, and there might be wish fulfillment, so don't read if that's not your thing. I've written it this way already, so if anyone still wants to flame me, I've got nothing to say. Everyone's welcome to join the group and pester me for updates! The group number is in my profile!
