#15x06

I'd like to talk about this book a minute. This is 15x06, when we see Cas again after he and Dean have... guess what? A Lover's Quarrel. Just like it says on the cover of this book.

I'm quite certain this book is a prop. Book covers do not look like that. Assuming with little doubt that this is a prop, that someone made with intent, then the message it sends if you notice it is absolutely intentional. Thus...

Destiel is canon.

Now we can argue whether or not Cas' feelings are reciprocated all day long — Dean never answered — but by this book alone... Destiel is IN the canon.

Because, if you ask me, it takes two lovers to quarrel. Dictionary definition agrees: "An argument between two people who are romantically involved."
