Yes, but no

"John? Oh, there you are. What are you doing?" His mother came over. "Never mind. I just came to tell you, Charlotte said she'd go bring your clothes back. Apparently she hid them at her friend's house. In the mean time, you'll just have to wear that."

"What? No. I can't. I need to--" he tried again to feel his way into the lock, the subtle stimulation of moving the cage teasing him even more.

But his mother stopped him, plucking the invisible key from his fingers. "What are you doing? You can't be running around naked with your aunt and I's friends coming over. We'll work it out when Charlotte gets back. For now, get downstairs." She paused to look at the tiny void between her fingers. "Such a tiny key. I better keep careful track of it. Fit for what it locks, though, I suppose." She turns and leaves as her comment rings in John's ears.
