Childhood Memories is the eighth episode of the first season.
One night, Sierra and Jacob were still feeling homesick.
"Maybe if you tell us about your home, you will feel less homesick," Murdoch suggested.
"Okay," said Sierra.
"What do you miss about your home?" Arthur asked.
"Everything," said Sierra.
"Okay, but what specifically?" Asked Rosie.
"One thing is my family," Jacob said, "especially my cousin, Rylie. She was one of my best friends. I remember every Saturday me, Sierra, Caroline, Rylie, my parents, my brother, my grandpa, my aunts, my one aunt's fiance, my uncle, and Rylie's brother and sister would go to a restaurant in the town we lived in for breakfast and talk about our week's adventures."
"What about Sierra's parents?" Harvey asked.
"Well, I, uh, never really knew my parents. They both died when I was little and since then, Jacob's parents took care of me," Sierra replied.
"That's so sad," said Murdoch.
"Yeah," said Sierra.
"Anyway, something else I miss is our tree house," Jacob said.
"And our climbing tree," Sierra added.
"Yeah, we had some good times in that tree," Jacob said.
"Remember when Cassie fell out and broke her wrist?" Asked Sierra.
"Yeah and then when you and I fell out and broke a bone and when Rylie broke a bone and then Kira, too?" Jacob added.
"Good times, good times," said Sierra.
"I wonder if Rylie still has that locket we gave her before we left," Jacob said, "That's it I'm calling her."
He then picked up his cell phone and dialed Rylie's phone number.
"Hello," Jacob said.
"Put it on speaker," Sierra demanded.
"Hold on a second, Sierra wants me to put it on speaker," Jacob told Rylie. "Ok now your on speaker."
"Hi guys," Rylie said, "What's up?"
"Nothing we're just feeling homesick and wanted to talk to you," Sierra said.
"Don't worry, I miss you too. I wish I could be there," Rylie said.
"We do too," Jacob said.
"Actually, maybe I can," Rylie told them.
"How?" Sierra asked.
"Tomorrow is the last day of school for the year. Maybe I could come to Sodor for the summer," she said.
"Great idea, we can come pick you up," Jacob said.
"How?" She asked.
"There's a railway line that runs in an underwater tunnel that goes from here to there, we can take Murdoch and come pick you up after school," he replied.
