I'm... surprised there's an "outside the mansion" at all, honestly. No mirrors out there, right?

[But why black and white? Seems sort of like it'd be extra effort to create a world that all adhered to a single palette. But maybe it's like... an old-timey 8-bit video game or something? Only using four colours saved on memory?]

Hey, what do you suppose happens if you pull a mirror off the wall and carry it outside? How far can you go and still have the mirror work? Does it like... project a bubble of colour or reality or something? Or could we dump all our mirrors in a hole in the ground on the beach somewhere and render them useless?

[Not relevant to their plans in the least. They're just... ha. They're just curious.]
