durrchesters:

Something caught my eye during Abaddon and Crowley’s ‘phone call.’ See that neon sign in the top right corner? Here’s another look at it.

And then flashback to season 5, Sam and Dean raiding a storage unit to find Michael’s sword, and getting ambushed by Zachariah. Where did they go?

We know the SPN set crew doesn’t throw stuff in just for the hell of it. Everything is methodically thought out, which leads me to this thought:

There’s something in John’s old storage unit that Abaddon either wants or has already acquired.

One way or another, this is definitely going to be a major playing piece in this season’s myth arc.
