Jack - Watch

As the young man rubbed his eyes and rose, his Servant Jack spoke.

“What’s wrong, Master? Are you having trouble sleeping? If you need to use the toilet, just say so. I will turn into spirit form and wait here.”

“...I just noticed, but being spoken to like this right after I wake up reminds me of those cartoon character alarm clocks.”

Flat was speaking to his left wrist. On that wrist was a steampunk-styled antique wristwatch, and Jack’s voice came from it.

“Normally I would already be in spirit form, but you’re the one that said ‘it’d be awesome if I looked like a spy,’ so here we are.

Jack was currently Flat’s personal wristwatch.
