Remus/Regulus
Remus was again wandering amoung small conversations almost aimlessly, picking up a word here or there, but not truly joining any. He liked being around the Weasleys because he could just be quiet and blend in amoung the others and they let him.
For the most part.
He might also have been hiding amoung the crowd a bit avoiding the possibility of being put on the spot again.
Contemplating taking his wandering into the orchard, he caught a bit of movement out of the corner of his eye and turned to see what had caught his attention. He smiled when he realised he was looking at Regulus and he gave up thought of the orchard for the moment and moved to join him.
"Enjoying yourself," he asked with a mischievous gleam in his eyes.
