Well, why don't you say a bit more about what is happening in the search? I know nothing about FBI or the process they'd go through to hunt for a kid in the area around Boston proper. Yet Ethan would have a general idea, so that could be useful. What does she plan to do, both in the near future and further? Is she making any plans, serious or not, about what she'll do if they don't find the kid in time? Also, where in Boston is her hotel? North, south, near the water, inland, etc. I don't need a street corner or a name unless that kind of thing entertains you. :)
Just... write what you would write if you didn't know that Ethan was coming in the next post, yeah? It doesn't need to be long, not at all. I just need a bit of setting, and some context.
