What I like about you?

Okay, well Val and Vic get married in the end right? In the beginning he was the boss of that place she worked and she liked him i guess. And then he goes to being a plumber near the end played by a different guy and they had a one night stand in highschool. THEN he's a fireman played by the man at the beginning. Did anyone else realize this? Or am I wrong? I'm sooo confused!
