Prompt: How Wheatley found out about April Fool's Day, Chell will never figure it out.
Chell woke up that morning to find herself with her head at the foot of the bed, and feet propped up on the pillow.
…She hadn't spun herself around at night, had she? There was no way she could've done this without Wheatley waking up…
And when she sat up, she saw that Wheatley was not in bed, as he so often was when she woke up to her alarm. Where was he?
Hearing a noise in the kitchen, Chell sat up, pulling herself out of bed and dashing out of the bedroom, only to see the sofa flipped upside down.
…What was going on? What was today… oh.
Oh no.
Chell rubbed her eyes, really hoping that the calendar was not lying to her, and that this was somebody else's doing, not Wheatley's.
But the text was printed clearly: April Fool's Day.
He was grinning like a fool next to her, and Chell wondered what she would come home to when she got back from work.
She stopped outside the door, having discarded her ridiculous, visually-impairing glasses long ago. Her task team at work decided it would be hilarious to hand them out. She really didn't see the point of this holiday, and thought that the waste of plastic for sunglasses and kazoos and paper for streamers wasn't necessary.
But her hand was hovering over the doorknob. How had Wheatley found out about April Fool's Day? And if he actually did know, what was waiting for her on the other side of the door?
Deciding she had to face it head on, Chell threw the door open, to a…
Relatively normal-looking apartment. The sofa wasn't flipped over anymore, Wheatley was instead reading a book on the sofa, turning and brightening when he saw her come in, looking mildly confused.
"Hello, dearest!" He placed the bookmark between pages and closed the book, turning himself so that he could watch her.
So there was something weird. What was it? She had no idea what Wheatley was planning to bring out for April Fool's Day.
The first thing she noticed was the table. The two chairs were flipped onto it, unnecessarily. Then, she looked into the kitchen. The fridge wasn't open, but Chell noticed all the magnets had been flipped upside-down. And upon opening it…
Luckily, there was nothing there that was wrong. Closing it, she walked back out, and sighed.
"You haven't noticed the big kicker yet?"
Chell's eyes, which had been steadily closing in relief, shot open. Wheatley was looking at her, grinning once again. She quickly looked around the apartment. There wasn't anything noticeably off. She turned back to Wheatley, who was still waiting, with a book in his hands…
And she saw it.
All the books on the shelves around their apartment had been flipped around. The pages were facing outward, spines hidden in the back.
How long had that taken him?
Finally, Chell started laughing. Wheatley had done such little mundane things, like spinning her around when she slept, flipping over magnets on the fridge, and just ridiculous things that only he would do. There was nothing harmful in any of them, just little things that were… foolish.
Things that made her laugh and smile, which always made her feel better.
Wheatley joined in, and spent the rest of the night helping Chell spin the books back around. It was totally worth it.
