Another year had come and gone and James had never been more excited to return home. Sixth year was a bit too stressful his liking. It would be good to sleep in the comfort of his own bed again, to not worry about waking up on time or stress over excuses as to why he was running late for class. He was looking forward to his mother's homemade cooking, lazy days with Sirius, and not having to deal with the drama brought on by teenage girls.
Before he could start his summer, however, James decided he need to attend to his unfinished business. Said unfinished business was somewhere on the trail in one of the many compartments on the Hogwarts Express. Thankfully he had time on his hands- it was quite the long journey back to King's Cross Station - and thankfully there were only so many places she could be hiding.
So James searched the train for Lily Evans, checking every single compartment and train car along the way.
