You hear sobs coming from the bathroom at Grim Pl. 12. Somehow you could hear it even in spite of the running water. You know it's Regulus who is in the shower and your heart squeezes painfully for him. Meanwhile, Regulus is sobbing in the shower, trying to scrub off his freshly etched dark mark. He's regretted getting it as soon as he got it, but now it's too late. It won't come off no matter how hard he scrubs against it. His skin bears red marks but the sign remains there, unchanged, unaffected, unyeilding, gaping into his face like a snigger. As you hear his sobs, you cautiously enter the bathroom. Regulus hears your footsteps and freezes.
"Who's there? Can't you tell it's occupied?" he asks, trying to maintain a composed tone of voice, attempting to hide the trembling in his voice.
