This short spoiler-heavy comic was commissioned by Imperfectxiii, featuring his OC dealing with Pinkie Pie after the time skip. The release of this comic was delayed until after the series finale to avoid spoiling things beforehand. The following description was provided by the commissioner:

It took Copper Plume a long time to get over his and Pinkie Pie’s breakup – a small part of him still hasn’t. But he would never allow himself to be bitter over it, and he was glad that Pinkie eventually found true happiness with Cheese Sandwich. And he had to admit… they made a cute couple, and Lil’ Cheese was pretty adorable.
