As the night wore on, Teddy dozed on the wrong side of the table, waiting for Hermione to leave his nook so he could reclaim it before sunrise. However, she seemed quite content to stay where she was with her little nest of clothes.
So, when the sun's rays finally did come through the window, they were still in the same situation. There wasn't anywhere to hide other than where Hermione was. Teddy would have rather been the one hiding, but in hindsight, maybe it was better that she have that spot. The situation was bound to be a lot more strange and disturbing to her than it was to Teddy. Still, he didn't enjoy shifting out in the open. Teddy decided to force the change faster so there would be less time to catch him unaware.
Forcing a transformation faster or slower on either side of the change was possible. However, Teddy rarely did it because it left him physically exhausted. Besides, it was usually useless. The change was inevitable. There was no way to completely hold it off. Well, no way to hold it off and still live, as Hermione's case illustrated.
By the time the sun had cleared the skyline, Teddy was already dressed and sitting in the only chair in the room. Hermione, on the other hand, still hadn't started her transformation. In fact, she didn't start to shift until the sun had fully risen. This time it took the normal amount of time to change back to human. Teddy was grateful.
When the change finished, he could hear her shallow breathing. He could only imagine what she was thinking, discovering her clothes scattered around her and no memory how she got there. When the rustling and scrambling noises of getting dressed stopped, Teddy cleared his throat.
All noise stopped from her corner.
"Look, I know this is an extremely bizarre situation to wake up to."
Hermione peeked around the table at him, an afro haloing her head, but her eyes were cold.
"I can explain," he said, holding up his palms up to assure her.
She whispered something and reached her hand out. With a rush of wandless magic, Teddy felt his body stiffening into a full-body-bind. As Teddy's body slipped off the chair, Teddy cast a wandless 'finite' to end the spell. He caught himself with his hands, his nose mere millimeters from the ground. He vaulted to a crouch and watched the young witch warily.
"Where's my wand?" she hissed, hand still outstretched towards him.
"I don't-"
"Why didn't you kill me like the others?" she demanded.
"Ki-Kill?" he choked. Then he realized what she meant. "I'm not the Moonlight Killer!" he said indignantly, standing up.
She took a step back, her eyes narrowed. "Then let me out of here."
He glanced nervously at the door, still magically locked from the outside for everyone's safety during the change. "Actually... I can't."
She immediately threw another wandless spell at him, which he dodged easily now that he was on guard. But he only barely ducked the second one she cast. By the time he stopped the second spell, Hermione had reached the door. He waited as she tried to open it both manually and with a useless alohomora. Turning, she glared at him.
