Hold Your Head Up
Based on a prompt by Astridianmayfly
There is a ghost living in Danny's mirror.
Evening time. The family is going out tonight—they're just waiting for Danny to finish getting ready. In his room, Danny is applying fresh deodorant to his armpits when he hears a noise.
"Seven…eight…nine…ten."
Either the voice in his head is louder than usual, or someone was spying on him. He looked around just to be sure. Nope—he was the only one there. Back to the preparation, then. Danny picked up a suit and a plaid button shirt and, holding them by their coat hangers, held them up in front of himself while looking in his wall-mounted mirror. He held up the plaid button shirt first.
"No," the voice from before said.
As he held up the suit, he figured out where the voice was coming from: his reflection in the mirror.
"There we go," it said regarding the suit.
"Oh come on," said Danny, as if it's all in his head, "It's the Rockatorium, not the Metropolitan Opera."
"Then why is your family all dressed up?"
Danny groaned. He put the suit and plaid button shirt down on the bed, and picked up a striped button shirt and a t-shirt. He held up the t-shirt first–one with a Dumpty Humpty insignia on it.
"A t-shirt in this kind of weather?" Said the reflection in the mirror, "Are you nuts?"
Danny held up the striped button shirt.
"Nah, that's not working either."
"How about if I wear this over the t-shirt?" Danny asked.
"You're overthinking it," said the reflection.
"I guess you're right."
"But don't under-think it either."
The pressure was too much for Danny. Either the figment of his imagination is out-to-lunch, or there was a ghost in his mirror. Thankfully, both were interrupted by a knock on the bedroom door. Danny knew who it wasn't—his parents had a bad habit of barging in without knocking; that's why he put a brick at the foot of his door. He moved the brick out of the way and let Jazz in.
"Danny, your ready to go?" she said, in her best, dark-purple dress.
"See, that's what I'm talking about!" said Danny's reflection.
"Oh great," Jazz groaned, "There's a ghost in the mirror again. I'll get the Thermos™."
As soon as Jazz shut the door, Danny faced his sentient reflection in the mirror.
"Uh oh," it said, "The jig is up."
Danny dropped all signs of impression.
"Who are you and what the hell are..." sigh, "Just get out of my mirror."
"Oh well, it was fun while it lasted," The reflection stepped forward toward the edge of its side of the wall, and stepped through, revealing the merry prankster behind it all…
"Hi, cousin!" said Dani, wearing a cute yellow dress.
"What the…?" Danny gasped, then sighed, "Aw, I can't stay mad at you."
He pet his little clone on the head. Dani blushed and smiled. She is adorable.
"So what should I wear?" Danny asked, realizing his mis-sorted his priorities.
"How about open plaid button shirt over the T-shirt?"
"Now we're getting somewhere."
Just then, Jazz came back, Fenton Thermos™ in hand.
"False alarm," said Danny.
Danny didn't know ghosts could overshadow mirrors. He made a mental note to try that some time.
When the three Fenton kids went down to join their parents, Jack and Maddie were watching TV and laughing—Spongebob was talking to himself in the mirror about courage and not panicking, only for the reflection to walk out on him.
