ok so I think weve pretty much decided a little sister might be kinda hard to explain. but how about 1 that was younger than Dean but older than Sam?
I think this would also be hard to explain as, even though Mary and John had their rough spots *cough 5x16 cough* i don't reckon John would have had an afffair in the 4 year between Dean and Sam each being born. What is this talk about a Winchester Sister?? Is it a new spoiler that's come across or something?? :S x
no because
1. that be Strange and just no
2. that would mean john or marry cheated on one or the other which they would never do!
It would not fit!! besides they have Adam The don't need a friken sister it would be a lame addition to the story.
A little or big sister whould be horrible. As much as I love the Winchesters I don't think a sis would be good 4 the show. AT ALL!!!
