"I told you!"
Sirius looked up from the book he was lazily perusing, the incredibly slow day having gotten the better of his boredom ages ago. He slipped his bookmark in and closed it as two people, probably a father and a daughter, stalked into the arcade, distracted by a heated argument.
"I told you! This power is nothing but trouble! The situations it gets us into aren't worth the perks!" the father yelled, a self-righteous expression on his face, but the girl who was probably his daughter merely glared.
"Don't be daft! Our power is something amazing, something that could be great! Why won't you let me use it?!" she pleaded, half-sad and half-angry, but the man only scoffed.
"Oh please, this power couldn't be great if greatness walked up and bit it on its-" the man started loudly, only to be interrupted by Sirius tapping a finger on his shoulder.
"Uh, yeah, hi. I couldn't help but notice this quiet and non-intrusive argument going on about three decibels over the sound barrier-" both of them blushed in embarrassment, "-and if you ask me, powers are something like swords. The level of greatness is directly proportional to the person that wields it. What seems to be the problem?"
The man took a breath, probably to assure me that they didn't mean anything and magic doesn't exist, why would you even say that, but the girl beat him to the punch.
"My father and I have the power to make anything we read aloud a reality, but he's too dense to notice the potential!" the girl he now knew to be Meggie exploded, gesturing wildly at her father, Mo. He shot a venomous glare at her, probably concerned about secrecy or some other nonsense like that.
"Our power is horrible. Nothing good can come of it!" he shouted, but he was distracted by Sirius pulling out a piece of paper and a pen, bending over the counter to scrawl something. He straightened up after half a minute, holding the paper up and looking to Meggie for comment as he recited what he'd written.
"And then suddenly, every problem the world had ever had was spontaneously solved in a way that created no new problems ever."
His piece said, he turned to beam at a flabbergasted Mo as Meggie looked on in triumph.
"Wh- but I- and you-" he stuttered momentarily, then huffed and glared. "Okay, fine. But how do we get home?" he demanded imperiously.
Sirius blinked. Several times in fact.
Then he looked at Meggie, asked quite clearly, "Was he dropped on his head as a child?" then scrawled underneath his solve-all phrase, 'And then, Meggie and Mo found themselves back at Elinor's house.'
He handed the paper to Meggie, confiding, "I actually don't trust him with this right now," and waved cheerfully at the two as Meggie read out the words.
The ink dropped off the page and flowed together into a circle, which then turned into a pitch-black hole in the ground. Meggie glanced at Mo, shrugged, and jumped in, followed closely by her father. The ink evaporated into nothingness, and Sirius gave a little smile before opening his book again.
