On Wincest:
A few examples of Wincest being textually included in the show (and this is just what I can post without running out of space)
Edit: I wanna point out that this is specifically just to talk about text thrown in by the writers. Love love! <3.
The ‘let’s be real, Sam was coming onto Dean’ scene from Playthings, not textual, but it needs to be here.
