Wepwawet stirred and reluctantly materialized in response to the compelling summons.
"Look!" Kevin piped in his cracking juvenile voice. "Jared's gone!"
The deity looked at the wall with disinterest and offered a laconic, "It appears so."
"Do something!" Kevin demanded. "Bring him back!"
"It's really best not to get attached to such lower life forms, whether they be collective or individual unicellular protists," the bored minor god chided the human boy.
Kevin balled his hands into fists, but in his moment of exasperation, he noticed a few specks of mold still clinging to the wall. He needed too squint to see them clearly.
"Wait! I think some of him is still there."
"Really?" Wepwawet feigned excitement and clasped his claw-tipped hands.
"Quit being a jerk," Kevin said. "Maybe I can grow him back with a few cell samples..."
"You must be a joy for your science teachers," Wepwawet remarked.
"Help me!"
In a flash, Wepwawet produced a glass petri dish and handed it over to Kevin. "Perhaps scrape him off into that," the deity instructed.
Lacking anything else, Kevin used a fingernail to scrape the last of Jared off the wall and into the confines of the dish. He remembered something from his research that such slimes needed moisture, so he walked to the sink and carefully introduced some water without swamping the precious cells.
"When you write this for your memoirs," Wepwawet said, "you simply must titled this section "My Brother, the Science Experiment."
Kevin would have responded with some sharp words, but the deity had already dissipated in a puff of spores scented like pumpkin spice.
As he took home the petri dish, he wished he had simply scraped his brother off the wall yesterday when there had been more of him.
"Don't worry, Jared. I'll grow you back."
Back home, he put the petri dish aside and began to Google tips for the care and cultivation of slime molds.
