I had completely forgotten that it took **2** leaps to get Sam and Donna married. I'd somehow gotten it in my head that they'd always been married in the original timeline, but that she'd left him because of her issues... two early leaps to fix/allow Sam's marriage, the last known leap to fix/allow Al's... Anyway, this story jolted around my canon memory and told me I need to rewatch some key episodes! I have the first season on DVD, thanks to my sister.
