Yes, Mr. Freeman, I was expecting something, and Jabba kindly provided it. Granted, it wasn't quite what I expected, but given the questionable sanity of GlaDOS I am willing to accept it. The key is that Nurses rarely work alone, and though they are usually the second for a Doctor, I am willing to accept that in this case our companion the White Witch was tied to Jabba the Bodyguard,
This brings me to our second point. Given that we did not have a kill last night, we are in a situation where the Havenites either are trying to pull a fast one, and Jabba is among their number, or Jabba has the name of someone they tried, and consequently failed, to kill. However, I also approve of his not mentioning who he targetted on either night just yet.
Given the nature of his role, and the fact that no one claimed against him I am inclined to trust that he speaks truth. This means that we can now make use of the full knowledge of how Gandalf acted, and use that to assist in judging the wizard. Once that is done, we can hear who Jabba defended on the second night, and have at least a small measure of certainty in our following discussion.
