I made myself comment even though I don't really know what to put.
This is so heartbreaking...but I guess that's the point! It is really well written and I hope you write more stories soon (though probably not this one cause Frank's dead :( ).
AHHHHHHHHHHHHHHHH;; That's... aww, fuck. That's so, so sad. You caught me on an insanely emotional day. But that doesn't mean I can't appreciate good writing. :] Awesome one-shot. But sad.
