One shot with alternet endings. I got the idea from my rp partner on tumblr. Thursdays-soldier.
"Cas…are you watching Breakfast At Tiffany's?" Dean looked over the angel's shoulder.
"It is a beautiful movie, Dean," The angel said, brow furrowed in deep concentration.
"Well at least Holly Golightly is kinda hot." The hunter walked off.
A week later something similar happened, "Singing in the Rain? Cas, what is going on with you?"
"I don't understand your outrage Dean." The Angel turned back to the television. Through the next week he watched every romantic move from An Affair to Remember to Sleepless in Seattle. Something was going on with him.
"Cas what on earth are you doing?"
"I'm studying, if you must know." He sounded annoyed, as if Dean were interrupting something important…it was Down With Love for god's sake!
"Studying what?"
"Human interaction." The angel said, glaring at the screen.
"This is not regular 'human interaction'!" Dean laughed, "This is just…like crappy movies."
"I am interested in romantic interaction."
And that was the end of that conversation.
