This was a really great take on the prompt. I love a good "deal with the devil" story and the fact that was the connection and we didn't know until the third version of the story was a great twist. All three characters were well-developed, and it was fun to see how the three different parts of the story connected with each other. Your character development was really good, especially given the word count restrictions for this contest; each character had their own unique voice which made each section of the story distinctive.

If there was a weak point in the story, I think it was the first version of the story told from Thomas' perspective. With the deal being made between the second and third character, Thomas' perspective is somewhat unnecessary and only adds to the story in the sense that he's the target of Constance's revenge. Given that you only used about half of the 300 word limit for that point of view story, I would have loved to have seen that part expanded and more tied in with the rest of the narrative. For example, what if the devil had made a deal with each of them and was collecting at the same time? Or what if the devil was there in the elevator to make a deal with him to save himself? It felt like there were some missed opportunities with how Thomas connects to the other two, beyond just being a foil.

Overall, I really enjoyed this story. I think it was well written and compelling, and you've got a great foundation to tell a really exceptional story through three different perspectives. Nice job!
