Episode 5 Discussion [re-watch]

[Naivety]

I was watching this episode today and noticed the very same thing for the first time. Harry notices the gesture, too. He watches her while he carries on listening to Gary. The other thing I noticed was when Ruth asks him if they're doing the right thing. He says something about it not just being about the murder of a friend or the book. I think he means they have to finish it because she is in danger. That's why he tells her to call when she gets to the safehouse.
