Brett Partridge is dead. That's a really twisted turn of events. However, Bertram stated something early in the episode, The Desert Rose. He said that "I am many things to many people" and pointed out that he sometimes was calculting and he had a "duplicity". 

He is mar...? Is that familiar? He is many? 

However, saying that he is many different things and saying that he has duplicity is at least something. 

In the end, when Partridge was lying on the floor dying, didn't it sound like he said Kirkland? Or something with a K? 

Well, I can't really take that for real proof. But it's something. 

My money is on Bertram, Kirkland or Haffner. But it would't suprise me if Heller did another crazy twist. 

Cheers.
