Looks fine. If you want Susana to get involved, post/PM some info about her so I can work her into the plot. I can run her or you can run her once she's involved (or both).<br/><br/>In general, you can run NPCs that you introduce to the plot. If there's a mystery you can't have them just know the answer, but they can know a guy who might know and so on. TL;DR: you can use your NPCs to advance the plot, but not to skip it.<br/><br/>Unless you pay Fate Points. Then we'll talk.<br/><br/>In general, anything can be made to happen with Fate Points.
