Dean felt the crash of water against the sides of his box – his coffin. He heard the sound get muffled, felt the cold water flood in. His heart hammered. He had done well not to think of this, up unto this point. Now, he wished he had thought some more.
Alone, he thought. I am alone with Michael.
He felt a shuffle beside him and jumped, not yet ready to face the archangel.
His head turned and his nose brushed against another.
Even in the pitch black of his own sinking ship, he recognized the scent.
“Hello,” Castiel said plainly.
“Cas!” Dean said, trying to sound cross but only sounding relieved. “How did you…?”
“I can turn invisible, if you do not recall.”
Dean couldn’t help the laugh that tumbled out of him, even as his chest was now soaking with frigid water.
There was a brief surge of light, and Dean felt different.
“You should be able to breathe fine now,” Cas told him, nose brushing as he nodded resolutely.
“You shouldn’t have stowed away, buddy,” Dean whispered, knowing it was too late, unable to stop the smile on his face.
“Well, who else was going to quote the entirety of Tombstone with me?”
And Dean was laughing underwater, lungs filling with liquid as he held Castiel close.
“I just can’t get rid of you, can I?” Dean said, words bubbling.
He felt Castiel smile. “Never.”
