This is an excellent episode. As Drusilla and Darla go on the rampage to quench their thirst, the people trying to controll it all, will learn that that some things are just beyond their control.
As angel hunts down Darla and Drusilla, he gets to the point where he must make a choice, and salvvaging the damned is just not his forte.
What a great moment to see that the people of Wolfram and Heart get the bill presented, that they had in mind for others.
There are moments in life when you just do not say 'come in' to a Vampire. Ehh.... that would be every moment i reckon. What a pity they forgot that rule.
