Aw, I'm so glad it ended on a touching note!
Ok here's my take: it's one of their first Christmases together, maybe one of Lois' first Christmases that's not supposed to suck. And instead of being together, SMan got called away on an emergency, leaving Lois to yet another year of staring out her window wondering when the holidays are not supposed to be so crappy...
