Well, the way Caitlyn worked through her initial anger and disappointment and related the other trainer's journey to her own. It shows just a bit of character development, which is always my favorite part of a story.
Writing style wise, I didn't notice any new typos, and the grammar was on point. Your word choice conveyed the sort of mysterious vibe I think you were going for, and you were showing, not telling. You trimmed out the fat and kept with what the story required, which is a good thing when it comes to word restriction. I felt like you got a lot of story out of a few words.
I feel like I'm echoing what everyone else has said, though, so just be reassured that you did a good job.
