Love is a powerful emotion, but even love has it's limits.
Vinyl and Octavia are as close as can be. Sure you can look past each other's flaws and see the beauty in each other just the way you are. But what if that flaw is too much to look past? The wild, alcoholic party tendencies Vinyl tends to exude may push the limit, but with not one ounce of responsibility to back her up, not to mention the countless broken promises and childlike actions stacking up on a daily basis, Octavia has had enough.
Now Vinyl, a mare deeply rooted in living in the moment, forgetful, and irresponsible, must grow to understand a harsher reality without love, and learn to appreciate the world more so than she did before.
