There is a section of the Bible that has been wiped from humans memories. It is about a woman,named Amirell Winchester,who is prophecied to save the world or end it,in the year 2013. It tells about how she is a hunter,with her brother Sam and Dean Winchester,and that there will come a time when she must make a decision which will change the world forever. The decision is known only to the writer of the small section in the Bible of man. But it gives you one small nudger.
She's half angel.
