Some people have been speculating that Amelia was pregnant with Sam’s child and seeing how short female characters’s lives are on SPN ( especially Sam’s girlfriends) i thought , what if Amelia dies and Sam/Dean are left with her son , Sam’s son on their hands ?
This season is “apparently” a back to the roots aka “hunting or no hunting , that is the question” and “John did the best he could , to raise kids in this world” and “family”
so what if Sam and Dean actually get to be in John’s shoes and raise a kid on their own too ? It’s a source of drama ( cause writers love that -_-’ ) and it’s also a way to strengthen the brothers bond on a completely new level. Dean raised Sam and he is gonna help him raise his son too.
Just imagine the possibilities.
