Lupin had a young face when he was in his mid-30s and light-brown hair which had flecks of grey. But because of the suffering he endured being a werewolf, he tended to look tired and pallor and his face had lines in it. He usually wore shabby clothing. He likes to touch you and his favourite way to do so is by wrapping his arms around your waist from behind or pulling you onto his lap whenever he has the chance. He got jealous easy and very touchy when other boys were around.
