Stardust Balance. Jack Wright.

Two versions of the same individual brought from their worlds into a cartoon reality. The former, transformed into a cartoon form to fit his new environment. The latter, reduced by age back to teenage form. And both are lucky enough to somehow earn the affections of the two greatest girls on that whole planet.

Unfortunately, one of them may not see things that way. For why, on Valentine's Day of all places, was Stardust seemingly giving Twilight the cold shoulder? And what was Jack's sudden behaviour of late acting like a male Pinkie Pie?

Sunset knows that's always something behind Jack's actions, but Twilight is beginning to worry about her own relationship with her boyfriend...
