Okay, because I'm mean, I'm going to have Ten's TARDIS show up on the observation deck. He can use his key and such to go in, but it'll just be her empty shell, nothing more.

And for Wash, this giant windmill and surrounding building stuff is going to show up an area of the woods between the Mayor's House and Luministi Greens East. The windmill moves VERY slow, so people can walk between the blades and shit and not get hurt. Heck, they probably wouldn't get hurt anyway if they were hit by the giant blades. You'd have enough time to move out of the way and let the blades carry on their merry way.
