I think I get where you're coming from, but imo this story satisfied the theme just fine. It may not be a typical "members of two different factions team up" kind of story, but I think the concept of the protagonist being saved through an unexpected encounter with someone who's there for an entirely different reason (looting the ship) should place the story well within the confines of the prompt.
We'll have to agree to disagree there, but I see where you're coming from.
To me, an allyship would involve active participation from both sides, but again, that's all within the purviews of your conundrum of philosophy.
It's still a solid story with great action and a thus-far greatly unique premise. I just can't give it full marks regarding how laid-out I feel the theme was and is.
