Intriguing!
I wish there was a little bit more background incorporated in. I don’t feel like the “Before” told me very much. Instead, there’s a lot of describing what Emily has done since then, so much so that it took away from what was happening, I got confused and didn’t realize she was still on the train. Otherwise, this seems like a very interesting story, and I’m interested to find out exactly what happened and what Emily plans to do next.
