if Lenny, who was in the military, heard the #s and went nuts....was Kate's dad?

I think that he very may well be because Kate's dad was in the military and we know nothing else about him...

connects hurley with kate, and we know everyone is connected somehow...

I don't think it is possible she mentioned Ft. Lewis as where he was stationed. That is in Washington State near Tacoma. And is a Ranger Base. Rangers are an elite infantry squad, not the type to get stationed at a listening post.

and she's known for telling the absolute truth?
