"You'll have to get in line," Remus returned with a grin. "I've already issued that warning in person." Granted, when he'd said it to James Sirius while the young man was dying, he'd said it to tease a lighter mood out of him. But, he'd reiterated the sentiment later with Sirius.
Following her gaze as they talked about Ted, Remus said simply, "He's in love." He hadn't talked about it with his son, of course. But, he, like Tonks, had seen him light up when he spoke of Victoire, heard the soft note in his voice. Remus had decided that, like Sirus and James, he didn't need to hear the words from Ted to be able to see the emotion.
He was just happy his son had found someone to stand by him.
