Though Bill found it unlikely that the shock of winding up in this horrid little place would ever wear off, that didn't stop his curiosity. When it was painfully apparent that his trunks would not open for anything (and apparently any amount of what should have been magic didn't work) he took to wandering around the small hovel-esque living arrangement. His wandering at least gave him the comfort to know that Ginny was here, too.
That came to an abrupt end with the ruckus of Tonk's arrival and the book he was holding flying right out of his hands and onto the floor.
Within a few steps Bill was at the door and peeking around at the person on his doorstep. You know, in case it was really a dragon or something.
"Merlin's pants!" He exclaimed, a bright smile crawling across his face. He threw the door open all the way, opening his arms for Tonks. "I never thought I'd see your face again."
