Harry: Hey boss, what’s that unicorn doing in our place?  
Winger: Oh her? She’s our new “runner girl” as a part of her punishment.  
Harry: Punishment? Like she’s a criminal of some sort?  
Winger: Something like that. Apparently her offences of law include: an illegal cult leadership, unauthorized tattoo removal, steal of rare spell, and attempt of destroying the time-space continuum and causing time paradoxes via unauthorized time traveling. At least that’s what I’ve been told.  
Harry: Wow! Now those are some serious offences.  
Winger: I know right? And yet, her punishment for all those crimes were nothing more but 6 months of community service in our HQ. I never asked for this, but Princess Twilight insisted that I should take her, told something that under our command she would learn some discipline.  
Harry: Wait, community service for 6 months? That’s it?  
Winger: Yeah, apparently Equestria’s laws are pretty forgiving compared to ours. She could’ve received a lifetime for those crimes, or even being executed. Eh, what you gonna do about it.
 
Now don’t get me wrong, I was actually pleased when Starlight Glimmer turned from the Darkside back to the Lightside in the season 5 finale. But still part of me wanted to see her get punished somehow for all what she did in the past (literally!), but unfortunatelly for my disappointment it never happened. But that’s what fan art and fics are for.
