"Twelve hundred years old, that's amazing," Steven replied, and set the little container of fishfood back down. "It must be weird when you go into museums and see things or copies of things you've actually used. Do you ever get the urge to correct them when they get the little labels wrong?"
He was still smiling as she asked about him explaining things, and shrugged. "I'm involved, yeah, and I would tell you but I still don't know all the details, so I'd probably get things wrong."
"I'll tell her, Steven," Marc said, and Steven nodded at his reflection.
"Okay, come on then. I left your coffee on the table."
Watching his reflection made things easier - it wasn't the sudden jarring change that they'd had at the start, where it felt like the person taking over was thrown into control, but it wasn't exactly smooth. Their eyes rolled back in their head, and it took a couple of seconds while the body just looked like it was staring at nothing, but then Marc stood up straighter than Steven had been holding himself, his shoulders back and his face clearly more guarded. "I guess it's easier just to show you." he said, his Chicago accent clearly nothing like Steven's London one.
