You did much to establish the relationship between the two, but there’s something that bugs me.. ah, the passive “As I descended that” and “I decided” and “Again, it’s all she seems to do”. These things are repetitive and unnecessary. They break up the action too much. What a great cliffhanger, however. The characters and setting are clearly defined as well.
It worked for me, and I think Elsha already hit my critique. The ‘By Lacy’ sentence confused me a bit too; I thought you meant there was a cry for help from someone adjacent to Lacey.
