Since it looks like she is going to have a prominent place in the last eight, maybe she deserves her own thread.
Why do I love this character? She may be the only person so far more murderous than Walter White.
Even Walt was willing to go along, grumbling, with the "hazard pay" for Mike's guys before that proved impractical.
Lydia's go-to solution for any problem seems to be "kill them all." Remember, her original idea about the train robbery involved murdering the engineers.
I also love the stark contrast between her willingness to set all kinds of death and destruction into motion at the drop of a hat and her inability even to look at it. Laura Fraser has done a great job with this psychopathic lunatic of a character.
