Put the cross into the centre of the Christmas Puzzle and Christmas is complete!
After finishing with the act about the magi you return to the puzzle on the board behind you. In shock you realize there is a hole in your Christmas puzzle. How is that possible? What are we missing? We have a Christmas tree, some lights, nice food and even presents. Why is there a hole?
You look for the last time in the folder and discover a giant cross. Why a cross? The cross is a symbol for the reason why Jesus came on earth. You can tell this as shortly or as elaborately as you want.
