Warehouse

Warehouses are locations commonly used by Sam and Dean for various purposes.

Overview
A warehouse is a location where goods or merchandises are often stored before distributed or sold. Some are known to become abandoned and thus become home to other beings, usually as a hideout or a base of operation.

What Is And What Should Never Be
Dean discovers a djinn using an abandoned, partially ruined warehouse as its base of operation, or nest. He is captured and forced into a fantasy world. Sam arrives just in time to rescue Dean and together they rescue the djinn's other victim.

Hello, Cruel World
Sam's hallucination of Lucifer tricks him into entering an abandoned warehouse. Lucifer taunts Sam and makes him fire the gun randomly. Dean arrives soon after and helps to convince Sam on what's real and what is not.

Repo Man
Jeffery lures Dean to an abandoned warehouse, where he has kept Nora's son. He then uses Dean to summon his demon. Nora and Sam manage to exorcise the demon from his vessel while Dean kills Jeffery.

We Happy Few
God summons his newly-formed team to an empty warehouse, where they discuss their plans and await for Amara to arrive. The team consists of Sam, Dean, Crowley, Lucifer and Rowena. Amara arrives soon after, at the beckoning of Rowena, and the team launch their attack.

Amara wanders in to the warehouse gravelly wounded, and for the first time in eons, she meets her brother again. God plans to lock her away again, but Amara manages to strike back and leave him in a near-death state. Lucifer is also banished from his vessel by her.
