Virginia:
Our mirror's smashed, what can we do? Where the hell are the other two?

Gustav the Magic Mirror:
Mirror one shattered be, by an oaf called Anthony. Mirror two is on a bed with barnacles upon its head.

Anthony:
A bed... with barnacles.

Virginia:
The sea bed!

Dwarf Librarian:
Yes. One fell into the Great Northern Sea. I think you can safely discount that one.

Gustav the Magic Mirror:
What you seek has not been seen, since it was stolen by the Queen.

Anthony:
The Queen! That's all we need.

Prince Wendell:
Anthony, uh, any chance of a little biscuit?

Anthony:
No, no, no, umm... Very helpful you have been, just tell us where we can find the Queen.

Gustav the Magic Mirror:
Near she is, but not alone. in a place that's not her home. In a castle, out of sight,where once the Queen was called Snow White.

Anthony:
That's Prince Wendell's castle.
