Thanks, The Spy of the Tiger. Ghostlight Sparkle haunts me now.

Ghostlight Sparkle drifted through the wall, poking her head out through a picture frame. "Hm. Interesting. Spike! Look up!"

Spike groaned, putting his comic book down. "What, Twii--HOLY CRAP, are you okay?!"

Ghostlight shrugged and finished phasing through the wall. "Yeah, why'd you ask? Also, I'm haunting you now because ghost reasons."

"Oh, okay then."

Spike went back to reading his comic.
