"Okay, but why Mom?"

"We are going to have a guest staying with us for a couple months. He will be at the train station at noon. Would you pick him up?" Sabine asked.

Marinette nodded and went upstairs to the guest room, her Kwamii Tikki, came out. "I wonder who the guest is Marinette."

"I don't know Tikki, but I am sure they will be nice." After she got the room ready she left to meet up with her friends. They were waiting at the park for her, "Hey Girl!" Her best friend Allya said as she waved to Marinette.

"Trunks! Come on, you'll be late and I have your stuff in capsules so it is easier to transport." Bulma said to her son, as he came into the room.

"Keep up with your training, boy." Vegeta said, "I don't want you to become soft."

"Yes, Dad, and I will see you in a few months." Trunks went outside and flew into the sky to go to Paris, France.
