No. She isn’t. She gets up from her table and walks towards the doors. He decides to follow her, shoving the last bite of his breakfast into his mouth he stands up quickly and strides out of the hall to follow her. He’s following her at a distance when he realizes she’s walking towards the Prefect’s Bathroom. He knows if she passes through that door he’ll never be able to follow her without being caught. Quickly pulling out his wand, he casts a silencing charm so she doesn’t hear his footsteps speeding up behind her and then a disillusionment charm as he gains on her. He’s able to slip into the door just behind her and slides against the wall so that he doesn’t jostle her or the door, recasting the disillusionment charm to make sure it holds in the new space. She stands just inside the door, checking to make sure she’s alone, and then turns to lock it. She pauses for a second and he thinks he’s been caught, but she takes a deep breath and turns, going to open the taps and select some scents.
