Jellyfish
"Lion's mane."
Ben studied the way Rey discretely raked her teeth over her bottom lip as she flipped over his biology notes. When she looked up at his prolonged silence, he pretended to struggle.
"…Cyanea capillata."
Rey nodded. She was doing that thing where she fit her fingernail between the wire coils of the notebook.
"Box jellyfish."
"Cubozoa."
"Moon?"
"Aurelia aurita."
"Commonly mistaken as a jellyfish," she challenged, picking tufts of paper out from between the coils.
"Portuguese man-of-war."
"You know these."
"I think, to be sure, we'll need to pull an all-nighter."
"Why?"
Ben's eyes glittered. "To not study."
