Early signs

[FLASHBACK]

"Hmm… hmm… mmm."

The young boy stopped mixing the fluids on the table and turned his head. His little eyes landed on the young girl with pigtails on the side. Her little arms were resting on the edge of the table, and her chin was on top of her arms. She was watching him do some science experiments but kept humming loudly, so he had to stop.

"Hera, what is it?" asked the young boy curiously. "Am I doing it incorrectly?"

The young Hera snapped her eyes up to him and said, "You're a weirdo."

"Huh?"

"Frank, how can you ditch me and Princess to do this?" she asked with a pout. "If you want to play with water, we have a large pool in the house. I can ask Bear to change the watercolor. He can make it a rainbow swimming pool if you want."

The young Frank blinked lazily. "This is not water."

"Then what is it?"

"Alcohol."

"Ohh…" Her lips formed an 'O' shape as she nodded.
