"Goodness... How much have you been thinking on this?"
"How can we not?" Cal asked, gesturing vaguely to where Joule had once been. "This is... it's terrifying! Y'know?!"
"Yes, I'm sure it is," Pop replied, nodding. "Cola was the same way, really. I don't... blame you for that kind of feeling. But I can assure you, that was actually what Joule and I had been talking about just before you arrived." He traced little shapes on the ground.

New personalities form and can be split off regularly with our power... There are options."
