"What about your planet?"
"Our parents' experiment was successful and our planet's atmospheric composition has returned to_" Seth said then started naming off numbers.
"In English?" Jack asked.
"Our planet has resumed to having the same type of atmosphere as your own," Sara said but still spoke in her computer-like way.
"Okay," Jack said.
"We wrote a book," Alex told the kids. "About our adventures with you a year ago."
"How long are you staying?" Jack asked.
"We have previously agreed on a chronological arrangement which states that we will be staying on Earth for an Earthling year," Seth said. Sara nodded.
"How will you parents keep in touch with you?"
"They are three million light years away how would we be able to make physical contact with them?" Sara asked.
"I meant how will you communicate with them?" Jack explained.
"We will use our devices to maintain contact with our home planet," Seth responded.
Jack and Alex nodded.
"Are you hungry?" Alex asked. The two kids nodded then followed Alex to the kitchen. When Alex handed them a bowl of soup and a spoon they just stared at it curiously.
Jack then showed them how to eat soup while the four conversed more.
