I've only watched this series off and on, but always liked Joe as well. He wasn't the traditional handsome hunk actor, but seemed very real and believable as an engineer (although an engineer married to someone with Allison's talents is a stretch...). I saw the series was ending and wanted to catch the finale, but was traveling. I doubt I'll track it down on the computer, so I don't mind being spoiled...how did it end? Did they really kill off Joe?
