As they neared completion of the repairs, Matthew and Sam realized that they had to be careful not to disrupt the timeline. 'If we're not careful, we could end up stuck in the past forever,' Sam warned. Matthew nodded, 'I've read about the consequences of time travel. We have to make sure we return to our own time.' With renewed focus, they finished the repairs and prepared the ship for takeoff. 'Are you ready, Matthew?' Sam asked, his glowing eyes shining with excitement. 'Yes, I'm ready,' Matthew replied, his heart racing with anticipation.
