In the first year, Remus was really sad and afraid until James and Sirius came into his carriage
And then, in the second year, Remus hoped that they will sit with him but wasn’t sure, and they came in the last minute, sweaty and breathless
In the third year, Remus saved for them a carriage and they all were sitting happily
In the fourth year he didn’t even need to save a carriage because everyone knew them and stayed away
In the fifth year Remus met them at the station
they finally arrived in time
In the sixth year he came with them because he slept in James’ house on the end of the summer
And in the seventh year, he kept waiting, but no one showed up. He tried to read a book but he just sobbed, broken, his tears dropping on the book, when he heard “PRONGS, A POLE” and saw a very concentrated James Potter on a broom, trying to avoid poles, keeping up with the Hogwarts Express AND saving a screaming Peter who hangs from the broom only with his right hand.
