Richard Grayson

Your older brother, Dick, had just gotten back from patrol, it was very late.
The first thing he did was take his mask off, before jogging up the stairs of Wayne Manor, and finding your bedroom door, knocking before entering.
He said your name quietly as he entered, just in-case you were asleep, but, when he entered he saw you laying on your bed, wearing headphones, presumably listening to music.
He smiled a bit before walking over, tapping you gently, "Hey."
