Sirius comes up behind him and Remus meets his gaze through the reflection, there's bone deep sadness in there, but also delirious happiness, crashing and meeting in the middle, creating a sort of unexpected serenity.

"Well," he starts, tilting his chin to the side as if he were going to turn to look at Sirius, but doesn't, instead he looks at them both in the reflection from the corner of his eye. "I wasn't exactly thinking about how it would look when I let it grow. It just happened."

He reaches behind him slowly, curling his fingertips to the hem of Sirius' shirt.

"I was... I suppose..." He pauses, licking his lips then continues after a deep swallow: "A bit of a mess, you see. Someone I--" The playful tone hollows out a little bit. "I cared about passed away."
