Summary
[---]
The boy did not cower. He did not cry, nor back away, nor flee. He stared, eyes wide and glistening with fascination as he drank in the sight of the massive creature. He took a bold step forward, the beast pulling back in a twisted, almost comically ironic fashion with the contrast in sizes of the two.
He did not cower, but instead smiled.

Aka my interpretation of Abaddon and the vessels friendship with a shit ton of waffling inbetween

Summary
First, I am just going to say, this is not a shot at anyone's religion in any way. If the religious references make you uncomfortable, you don't have to read this.
Since the second season is still however long away, I'm working out my obsession with a fic. This takes place after the first season. Abaddon goes to find bones, and ends up running back to the hotel with the ghost of a rather angry priest right on his trail. I am currently obsessed with the Nathan and the priest ship, so yeah, they gonna be gay, and they gonna crack...eventually. We gotta do some sad shit first.
