This was a fun story, thanks!
I do think the adherence to theme was your weakest category. I definitely see how this does fit the theme of unlikely allies, but I wish it felt more like Grek and the foreman had worked together to get out of the cell. In this version of the story, it felt more like Grek escaped than the pair of them escaping.
I enjoyed your writing and am looking forward to more in future writing jams.
