Great chapter, as usual. I love your characters. It's still a little hard to keep track of the names of the characters in the Australian subplot. I think that will get better for me as the story continues. It's great the way you made your engineer long winded and geeky. (I've met a few like that.)
I think the shadows have some kind of enbarasing sectret that could be uncovered if someone started poking around. I'm thinking something along the lines of a drunken encounter with a guy maybe in an airport bathroom. Well, maybe not the bathroom part.
The birthday gift was great. Hmmm, what could we get a young rock musician? I know! A book about decorating. I'm sure he will love that!
