They both looked at Hermione warily as she tried to get further away. There was a door to her left, and she made for it. Both Malfoys behind her were speaking insistently, but she ignored them. She pushed on the door, which moved like it weighed a thousand pounds. Throwing her whole weight onto it made it move a few inches. Why was the door so heavy?! Finally, Hermione got it open enough to squeeze through and saw a bathroom. Stepping inside was like walking through treacle. She slogged through the viscous air and slammed the door shut behind her, sliding down it to pant on the floor. Breathing was difficult. She was feeling light-headed.
