Harry's feet stopped moving when he saw the dementor and his head cocked to the side. No, not a dementor. It had only a tiny speck of Dark. A boggart. How cute.
"The Dark holds no more terrors for me." He told the shapeshifting non-being and walked past it.
Apparently miffed by the dismissal, the boggart grabbed his shoulder as he passed it, forcing him to stop. Harry turned to look at it and stared at its now unhooded face.
A few tufts of long black hair still clung to the skull and empty eyesockets peered out of a hollowed, beef jerky version of his own face. It probably wasn't an accurate depiction of a dementor since the soul harvesters were only partially physical, but it was the image that Harry's mind had conjured up.
"Alright, so maybe the Dark holds one more terror for me." Harry conceded, his eyes starting to glow as he pulled on what Light he could reach now that the Sun had set.
Fortunately, he didn't need much. Once he had it, he slammed his palm against the boggart's chest and released it, banishing the speck of Dark that lay at its core. The boggart dispersed out of existence without a sound.
"You should have stuck to jump scares."
