the reason is fangirls talking to each other

Introducing my little brother to Supernatural was the best thing I did in my entire life.

Now he is a Cas!boy (and probably also a future Destiel shipper) and I have finally someone who I can endlessly fangirl with; we literally just spent 2 hours sending each other SPN reaction gifs and basically having a decent conversation through said gifs. We also discuss every episode, analyze it, find symbolism and talk about legends and beliefs all over the world. It’s super important to me because our sibling bond weakened since I moved from my parent’s house 3 years ago; now I’m 22 and he’s almost 18, so it’s much more difficult to find something in common than when we were kids. 

Another reason to love this show.
