Remus stumbles through the shrieking shack and bursts through the door, taking note of Harry, Ron and Hermione who are huddled together in the corner. The tall scarred man standing between Sirius and the children.

“Oh come on Remus you don’t recognise me?” he says dramatically, his arms dropping down his side “12 years inside a triangular block of depression do this to you” you say once more, your once shiny, lush curly raven hair, now a matted dull black. A growth in facial hair across his top lip and throat. And the now sunken in features of his once handsome face
