After bandaging up Scootaloo’s leg, comforting her when she starts crying, giving hugs and a sweet treat, Windy starts telling the little filly some stories about Rainbow Dash. While she was talking, Scootaloo falls asleep. Windy finds it so cute as she covered the child with a red and white blanket. She was about to go off to continue cleaning some dishes when Scootaloo sleepily said “Thanks, Mom.” which made Windy leak tears of happiness (Knowing that Faust had blessed her with another child) and she decides to stay with the filly, both of them enjoying the precious moment as mother and daughter. ^^
