101 reasons to ship Sam & Castiel

This is for all of my fellow Sastiel/Sassy shippers! I figured it was time, considering this ship has material enough for more than 101 resaons tbh and I actually had some that I couldn't include.

I'd like to give a special thank you to tumblr users:
semirahose, bestiesandagents, an-angel-of-the-winchesters, infeffableslytherinkingintardis, and eruthiawenluin. I couldn't have finished if it weren't for all of your suggestions! I wish I could have included every single choice, but I had too many in the end. If I choose to expand it in the future, I will surely include them all.

Songs:
O' (Fly On) Orchestral Remix - Coldplay
Human instrumental - Christina Perri
Whispers Instrumental - Dave Baxter
Rise - John Dreamer
