Scootaloo was always the little filly that Rainbow Dash loved dearly, and Rainbow Dash was always the one pony Scootaloo admired fairly. Years have passed, ponies have aged, seasons have changed, and the weather has been controlled. This day, isn't like any other day that Scootaloo has passed. This day could almost be the worst day of her entire life, which the punishment is even worse than getting killed by the Headless Horse.
With Scootaloo in her juvenile age and grown to a young lady, she knows that Dash is going to give her lectures and a lot of tips on life instead of fun and games like they used to do in the old days. If this problem of hers doesn't work out, she wants to get in a hole and just die from sadness. She might lose her pride, she might lose her dignity,

Maybe, she'll lose one of the most precious stuff she ever had,
Rainbow Dash's Love for her...

After the fall of the Crystal Empire and the tragic Wedding of Princess Cadence and Shining Armor, Both King Sombra and Queen Chrysalis' whereabouts are unknown, same as the fate of the changelings even though some of them survived and could be seen once in a while.
They say that King Sombra became an outcast, regaining his power each day but may not recover from the nightmare Princess Luna gave him and Queen Chrysalis? She might be in the marshes, going around trying to find her changelings and regain power as well, seeking revenge.
No one really knows what will happen between the 2 villains when they meet.
Will they be friends or foes? or will they be more than friends, maybe the perfect evil couples?
