You’re Fundy’s younger sibling. In this au, Wilbur found and adopted Fundy but you and Tallulah are his biological children. One night, you and Fundy (who is a child in this au, he and you are five years old) had a nightmare and both ran to Wilbur’s room, leaving Tallulah asleep in the bedroom you three share. You both ran into Wilbur’s room, climbed up onto the bed and laid down next to him on opposite sides.
You’re a daddy’s girl so you clung onto Wilbur like you’d die if you didn’t and Fundy just… hugged him. You both immediately calmed down and relaxed when you felt him rubbing your hair.
He hummed quietly, before singing to calm you both down. “Kiss me once and kiss me twice, then kiss me once again. . It’s been a long, long time. Haven’t felt, like this before, since can’t remember when. It’s been a long, long time.” He went on, humming the same words in an upbeat yet calm tune.
Fundy’s tail drooped to the side and fell asleep almost instantly while you just held onto Wilbur but was calming down.
