Regulus is spending the summer at the Potter’s beach house since him and Sirius got away from Grimmauld Place. You are at the beach watching James surfing while reading a book and sat on the sand, it’s just the two of you and you two don’t speak very much.

James eventually gets out of the sea, with the beach surfboard under his arm and his brown curls all wet, with a bright smile. He is walking towards Regulus and says:

“Regulus, I should teach you how to surf”.
