I was cleaning out my notes and found this little drabble from way back when I was in this fandom and decided to post it to keep all my writing together. Enjoy.
If there is one thing Mary Winchester knows without a shadow of a doubt, it's that her son is head over heels, totally infatuated, completely in love with Castiel Novak.
It doesn't take a rocket scientist to see it in the way Dean looks at him, or in the way his whole body drains of tension whenever Castiel is around; Dean laughs more when he's with Cas than anyone else Dean ever talks to.
It's the same way with Castiel, with the way Castiel's eyes grow soft whenever he looks at Dean, in his gentle touches, or in the look of complete and utter adoration that shines whenever Dean smiles.
Yet what she doesn't know is how on earth these two haven't figured it out already - her boys have got a crush.
