Seamus, Dean, Ginny and Lia [!Grabme?]
"C'mon, he's definitely around here somewhere!" Seamus held Lia's hand and practically dragged her down the corridor of the carriage, looking in every window to try and find Dean. There were certain traditions that needed to be kept alive, and sharing a compartment with his best friend at the start of the journey was one of them. Seamus would eventually give into his fidgeting and go exploring down the train, but to start he and Dean would sit together and watch London melt away into the countryside. Obviously the two of them not had the chance the previous year due to the extenuating circumstances of having an anti-muggle army in charge, so this year he was quite excited to be back to it!
He'd lost Dean somewhere on the station in the confusion and his own relentless energy, but Seamus was certain his friend would be in one of these compartments. The train lurched as it left King's Cross Station and began to pick up speed and Seamus stumbled slightly. "Aha!" He declared as he finally found the familiar face he searched for. He slid open the door and flopped down on the seat opposite his best friend, "Alright Dean! Ready for another year of boring classes?"
