"So… should we be hiding from the recordings?" asked Kat.
"Eh, it doesn't really matter. The summoning circle should disrupt spells that record voices. They can see us, and maybe lip read? Not sure about that second one but they definitely can't hear us," explained Sue.
"Why? That seems specific… or at the very least not a coincidence," said Kat.
"That's because it IS. Dad talked about it once, apparently it's to stop people trying to make Contracts over long distances. This way they can't make a flimsy Contract but stay far enough away that they're hard to find. People need to be nearby to make a Contract. Well, I'm not sure if they NEED to but things certainly make it hard for Contracts to go through if they aren't nearby," said Sue.
Apparently Sue is demanding character development. No idea how it happened truth be told.
