DarkLady, I don't think Julia has even heard of the Collinses at this point. She certainly knows she's on the track of something big - but she doesn't have all the details yet.
Was this the first day that Julia lied to Dave Woodard? She has kept information from him, but she hasn't entirely shut him out, and we haven't seen her lying to her before, have we? I'm wondering if she wanted to bring him in on this project, but finally decided today that he would not go along. In the beginning of the episode, she was combative with him, but by the end of their scene together, it wasn't worth her time to fight with him: she just lied.
What's Burke's problem with how Vicky feels about Josette? He doesn't know how the music box entrances Vicky. He just has a knee-jerk reaction of no. Mitchell Ryan had a quizzical look that would have helped this scene along, but Anthony George just plays the dictatorial male.
