LAST EDITED ON 07-16-13 AT 03:08 PM (EST)McCrae said he didn't know himself how he was going to vote. There's no way Howard could have known how McCrae was going to vote if McCrae himself didn't know.
So no matter what he said about knowing that Nick leaving, he could only have suspicions, not certainty. He certianly realized that there was a possibility that might happen, but he couldn't have known for sure.
And if he didn't know McCrae's vote, he most likely was also somewhat undecided on Amanda's vote, although he probably did suspect that she very well could be against Nick staying.
And according to the edit, Jessie was also undecided up to the end too. She is a true floater this season, and could very well have thrown in with the girl's team as far as Howard knew.
