i was reading and i like the story alot. i'l be your beta if you haven't picked one yet. oh and a mary-sue is like a character (particually a female) who is described as being good at everything and very pretty. they are also usually paired up with a main character (but dean and sam are so cute, how could anyone not make up a character to pair them up with?).
The bizarreness of this review is caused by the fact that this person wants to be a Beta. A Beta. With conventions and grammar like this, they want to fix someone else's writing. Dear Gaea, that gave me the giggles.
