"Okay, love," Remus said, coming to Tonks' side and wrapping a hand affectionately around the back of Gabriel's head. "Time for you to go and have a fun night with Mummy. You'll be good, right?"
"Ya," Gabe repeated. "I'll miss you."
"I'll miss you too, bug," Remus said, kissing his son on the cheek. "Don't eat too much ice cream. I want you to sleep well so we can cuddle in the morning, okay?"
"Mhmm," Gabe said, eyes lighting up at the mention of dessert.
"I'll see you in the morning, okay?" Remus said softly to Tonks, leaning in to press his forehead against hers and kissing her. "Have a good night. I love you."
