Princess Luna will never be on my 'least fav' lists by virtue of her having a purpose in the rest of the series, even if I do think she's more than a tad bit overrated; or, 'unneeded' in a lot of episodes that involve her. Fan fics involving Luna also tend to be this for me...but not so for this comic. For the grimdark show-accurate rendition of a black comedy-joke story, Luna being the one to comfort Twilight and head Pinkie Pie's questioning was a bizarre stroke of genius, especially as PieSinful's comic is all about sincerely asking what the reality of Pinkie being a murderer means for the entire show and all it's characters. Princess Luna was saved from her most evil self by Twilight and Pinkie Pie. And now, that evil self is looking back at everything around her in absolute horror.
