I don't want to see ANY of the characters leave the show - they all play against each other, creating a complete picture. Loose one and you've lost the entire show. I hope to goodness that Leonard is just "out of state on a temp job" like the North Pole job and the Space Flight job. I'd hate to see the show without him. I'm pretty sure the writers know this would NOT be beneficial to the series and are just "giving us a scare for the finale" ... which, by the way, I HATE and wish they would NOT do that.
