Ned rushed up to Hank. "What's happening?"
"Someone's put some sort of...sudoku lock on the door."
"Sudoku...Na--Wendy brought some of that back home from her trip to Japan. Let me see if I can help."
"Be my guest, I've already placed the 3's, 6's, and most of the 2's..."
A few minutes later, the puzzle was complete.

The lock snapped open just as Rod and the others arrived. Ned and Hank glanced at each other, then opened the doors...
Wendy emerged from the cloud of gas, coughing and dragging Edward with her. She tore the breath mask from her face and slumped against the wall, exhausted.
