Pisces always called Scorpio an idiot.
"Wait, where are we going?" Scorpio asked.
"We're going to the pool, and you asked if we could," Pisces said.
"Oh yeah. I forgot," Scorpio said.
"Heh, idiot," Pisces said.
"Yeah I am an idiot," Scorpio said.
"But you're my idiot~," Pisces said holding his hand.
"Yup," Scorpio said holding her hand.
