Jake was not a fighter in the least bit. He knew how to defend himself and that was it. Not that it did much good with someone like Octavia. He'd found that out the hard way. Something about looking like some guy she knew. Not that he'd paid much attention to said guy. He didn't really matter.
This city was, compared to a lot of places, pretty messed up. Not that he had to worry about it. They took care of their own. Meaning himself and Octavia. She took care of him and he attempted to take care of her.
