After the Captain lost consciousness, she experienced a hallucination the likes of which few people had ever seen and lived to tell the tale.
Let it be known that the Captain was not a teller of tales. She never did tell her friends what it was that she had seen. For one thing, she would have had to explain the "Santa Claus was the monster in my closet" story, and she didn't want to get into that. It might get back to the Scarecrow one day, and then she would never live it down.
It will have to be enough to say that the Captain took a magical sleigh ride to the North Pole as the Joker's copilot, faced her childhood fears, discovered the true meaning of Christmas, performed a lavish musical number with Frosty the Snowman and the Snow Miser, discovered and subsequently forgot (for the fourth time) the meaning of life, trained in a forgotten martial art with a cigar-smoking elf who bore a striking resemblance to a diminutive David Bowie, discovered the meaning of figgy pudding, and on the whole came away better for her hallucinatory experiences.
She woke up gasping, "Pudding!"
Her friends were by her side in an instant.
"Captain," Al said urgently. "What's seven times four?"
"Pudding," the Captain repeated dazedly. Al sighed with relief.
"She's okay."
"How do you feel, Captain?" asked Techie.
"Funny…"
"Funny ha-ha or funny peculiar?" she had to ask.
"Funny…radioactive." She blinked at the light shining in her eyes. "Did you get halos, or is that the Star of Bethlehem?"
"Neither, smeghead. It's a fluorescent light. You're in a hospital bed. And, yes, you do need to be here, so I don't want to hear any argument. Another minute without the antidote, and you'd have laughed yourself to death."
"Oh." Captain shrugged. "Okay, then. But why did he squirt me?"
"Spreading holiday cheer," Al guessed. "Half the people in the ER looked way too happy to be there."
"Okay, then. I'll remember not to mouth off about Christmas crap next year. Can we go now?"
"They probably want to keep you here for observation," Al said doubtfully. The Captain squirmed.
"I hate hospitals," she muttered.
"Seconded," said Techie.
"Thirded. Every time I show my face in a hospital, someone dies."
They left by the window. Since the Captain hadn't been given a private room, this caused a bit of a stir. But they were past caring.
