So my observations this time are:

* I was surprised when I found out that Lux was related to someone like Trip Fontaine. I think that her parents found out about this, and they grounded her badly. This might have led her to suicide. Or maybe I'm being a bit exaggerated...

* Mr Lisbon is obsessed with having her daughters under control to a point that they seem like strangers to everyone else. But when he finds out about Lux and Trip (he probably found out about this) maybe he feels that he failed as a father, and he tries to fix this becoming more strict.

* I know this has few to do with this reading, but where did the boys come with the idea that all the Lisbon girls were like Lux?
