Starlight is now on the path to reformation, but judging from her behavior as of late, it'd seem she still has quite a ways to go. It's become apparent to Twilight and her friends that Starlight is having a difficult time letting go of her questionable ideals about friendship. But they won't give up on her, not yet anyway.
However, Starlight's greatest challenge in changing herself for the better has now reared its head in the form of Laughingstock; a pony whose cutie mark she took but failed to convert to her ideology back in her village. He's now in Ponyville, desperate for work as his cutie mark is still mysteriously missing. As imagined, he's not happy with Starlight in the slightest. After all, living without a cutie mark but bearing one that reminds him of just who did this to him would make anyone mad.
Not helping is the fact that Starlight doesn't seem to feel too sorry about it.
Rated T for language and unfortunate circumstance.
