After leaving the others, Berry was doing research in the main observation room by watching a video of Anna's fight with Pollution.
"The battle only lasted three minutes," said Berry as she noticed the time on the recording.
"Oh, is something wrong, Berry?" asked Kalia as she walked in, surprised to see her granddaughter there alone.
"I'm trying to figure out a way to help us defeat Pollution," said Berry without looking at her.
"I think you and the others may be rushing too much, some days it's better to take things slow," said Kalia.
"Rushing, that's it!" said Berry as her eyes went wide at an idea that had come to her.
"What is?" asked a confused Kalia.
"Spirit Aura gives a person characteristics of their Spirit Animal and that must include their heart rates," said Berry.
"A normal adult human's heart rate is between sixty and one hundred beats per minute," said Kalia.
"But hummingbirds have a heart rate of one thousand two hundred and sixty beats per minute, and Aunt Anna fused with five spirits including her own," said Berry.
"That would put her heart rate at seven thousand five hundred and sixty beats per minute," said a shocked yet horrified Kalia.
"I'm surprised she was able to last three minutes with a heart rate that fast," said Berry.
"But even if we know this, how can it help?" asked Kalia.
"Because now I can figure out how many Spirit Animals we can each hold at a time," said Berry as she started to work on gathering information.
"Good luck, Berry," said Kalia with a smile as she walked away.
