Well, they're really only present for one extended scene at the Burrow over the Christmas break. And Remus is a grouch. :(

Molly offers once again if they want to just stay for the holiday, but Tonks explain that he's worst... sometime around the moon. (I didn't catch it as I had a group of sniggering teens next to me.) At that point though, Remus notices something in the field before them. Tonks says, "What is it, sweetheart?"
