It's tough being a big brother having to babysit your little sister. When you have to babysit her while waiting for your girlfriend to come so you can confess your love to her...its even tougher. Let's watch as Shining Armor, professional big brother and monster slayer, has to deal with a Twilight Sparkle and her runaway imagination. Lets watch as he has to protect her from the monsters that live in her dreams and hide in closet; all the while trying to set up the perfect sate with his lady-Cadence.
Easy, after all...there are no monsters in your closet, right?
