Well, if Xander made that casket, I give him real props for the satiny stuff inside! Caskets....not easy to make and hold. Plus the headstone!
Even if they didn't bury her in the cemetary, they'd still have to buy these things that aren't you're everyday items you can pick up at Walmart. (Then there is the Xander or Magic option) and yet still, even if they bury her outside of the actual cemetary, you'd have to figure that with her name and everything on it, SOMEONE would eventually stumble across it. It's not exactly legal to just bury people willy nilly where ever you want. Especially if hiding the death all together.
And, why would Giles go along with any of that? It seems like he'd want her to have a "decent" burial. Not hidden in the woods with a black market head stone and casket on the off chance someone would try to bring her back.
There's the whole Dawn thing, but HE wasn't staying to take care of Dawn. I find it hard to believe, even as much as he seemed to dislike Hank's idea of parenting, that he'd believe Dawn was better off with two unemployed witches, a robot, (Xander and Anya MIGHT be okay) and an obsessed vampire with a chip in his head.
I mean, I love them too, but they'd hardly be the motley crew I'd will my children to in the event of my death!
LMAO! Yes, "We don't mind paying a couple thousand....it's gonna be a REALLY good play!"
