The one

-After the events of Magic Duel-

Trixie was accepted on Ponyville for a while,so Rarity decided she could stay on her boutique.

Rarity had to buy some stuff,so she decided Trixie could take care of Opal.

When Rarity was gone she decided to confess Opal what she felt.

-Oh,Opal,I love you so much I can't even say it.

Trixie used a spell to make Opal talk.

-I love you too Trixie,and I will love you forever.

Trixie felt her heart exploded.

-Oh Opal I always loved you...

-Me too.

-We should prepare the wedding.

-Of course my dear.

And everything was ok,the end
